Which of the following could be the side lengths of a triangle?
A. 2, 3, 6
B. 9, 10, 19
C. 5, 8, 15
D. 12, 15, 25
Answer:
The answer would be D. 12, 15, and 25.
Step-by-step explanation:
The first two sides, sum must be larger than the third side.
so 12+15=27 which is larger than 25
The correct answer for the side lengths of a triangle is D. 12, 15, 25.
What is the side lengths of a triangle rule?The sides of a triangle rule asserts that the sum of the lengths of any two sides of a traingle has to be greater than the length of the third side.
If a,b,c are the sides of the triangle then,
a + b > c
Now in the given question let us suppose a,b,c be the length of the sides
A. 2, 3, 6
Here, a = 2, b= 3 and c = 6
Applying sides of a triangle rule,
a + b > c
⇒2 + 3= 5 which is less than 6
Here, a + b <c
Therefore , these are not the lengths of triangle.
B. 9, 10, 19
Here, a = 9, b= 10 and c = 19
Applying sides of a triangle rule,
a + b > c
⇒9 + 9= 18 which is less than 19
Here, a + b <c
Therefore , these are not the lengths of triangle.
C. 5, 8, 15
Here, a = 5, b= 8 and c = 15
Applying sides of a triangle rule,
a + b > c
⇒5 + 8 = 12 which is less than 15
Here, a + b <c
Therefore , these are not the lengths of triangle.
D. 12, 15, 25
Here, a = 12, b= 15 and c = 25
Applying sides of a triangle rule,
a + b > c
⇒12 + 15 = 27 which is greater than 25
Here, a + b > c
Therefore , these are the lengths of triangle.
Hence,The correct answer for the side lengths of a triangle is D. 12, 15, 25.

Factor completely
4x^2 - 18x - 36
Answer: 2(2x + 3)(x - 6)
Step-by-step explanation: For any factoring problem you do, your first
task will be to determine if a GCF exists for the original polynomial.
If a GCF does exist, it must be factored out as the first step to the problem.
In the problem you see here, the 3 terms in
the original polynomial have a GCF of 2.
So a 2 must be factored out as your first step.
This leaves you with 2(2x² - 9x - 18).
This does not make your life a whole lot easier however
because you still have a coefficient on the x squared term.
Factoring from here, you get 2(2x + 3)(x - 6).
Answer:
2(x - 6)(2x + 3)
Step-by-step explanation:
There are a few steps to factoring depending on the polynomial.
Step 1. Factor our a common factor if possible.
Every term is divisible by 2, so factor out a 2.
4x^2 - 18x - 36 =
= 2(2x^2 - 9x - 18)
Step 2. We need to factor the quadratic trinomial.
Now we have a quadratic trinomial, in which the x^2 term is not plain x^2, but it has a coefficient of 2.
Our polynomial is of the form ax^2 + bx + c, with "a" not equal to 1.
We have 2x^2 - 9x - 18, so we have a = 2, b = -9, c = -18.
We can try guessing, but instead, I will use the "ac" method.
Step A. Multiply coefficients ac:
ac = 2(-18) = -36
Step B. Now we need two numbers that add to b and multiply to ac.
We need two numbers that add to -9 and multiply to -36.
The numbers are -12 and 3 since (-12)(3) = -36, and -12 + 3 = -9.
We now break up the middle term, -9x, using these two numbers.
= 2(2x^2 - 12x + 3x - 18)
Now we factor by grouping. Factor a common factor out of the first two terms, and factor a common factor out of the last two terms.
= 2[2x(x - 6) + 3(x - 6)]
x - 6 is a common factor inside the brackets, so we factor it out inside the brackets.
= 2[(x - 6)(2x + 3)]
= 2(x - 6)(2x + 3)

The total rainfall for two days was 14.6 mm. The first day's total was 4.5 mm less than the second
day's. How much rain fell on each day in cm?
Answer:
first day = 5.05mm = 0.505cm
second day = 9.55mm = 0.955cm
Step-by-step explanation:
Let x represent first day
Let y represent second day
x + y = 14.6
x = y - 4.5
(y - 4.5) + y = 14.6
2y - 4.5 = 14.6
2y = 14.6 + 4.5
2y = 19.1
Divide both sides by coefficient of y which is 2
y = 9.55
Substituting value of y in the equation x + y = 14.6
x + 9.55 = 14.6
x = 14.6 - 9.55
x = 5.05

Someone please help! :(
Answer:
See below.
Step-by-step explanation:
Start with triangle ABC with side BC lying on line n.
Draw a line through point A parallel to line n, and call it line m.
Angles 1 and 3 are alternate interior angle of parallel lines and are congruent.
Angle 2 and 4 are alternate interior angles of parallel lines and are congruent.
The sum of the measures of angles angles 1, BAC, and 2 is 180 since they lie on a line.
m<1 + m<BAC + m<2 = 180
Now we substitute in the angles we know are congruent by alternate interior angles (written above).
m<3 + m<BAC + m<4 = 180
Solve each equation 9-4(2x-1)=45
I think it is done like this but I am not sure.
Simplifying
9 + -4(2x + -1) = 45
Reorder the terms:
9 + -4(-1 + 2x) = 45
9 + (-1 * -4 + 2x * -4) = 45
9 + (4 + -8x) = 45
Combine like terms: 9 + 4 = 13
13 + -8x = 45
Solving
13 + -8x = 45
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '-13' to each side of the equation.
13 + -13 + -8x = 45 + -13
Combine like terms: 13 + -13 = 0
0 + -8x = 45 + -13
-8x = 45 + -13
Combine like terms: 45 + -13 = 32
-8x = 32
Divide each side by '-8'.
x = -4
Simplifying
x = -4
The solution to the equation 9 - 4(2x - 1) = 45 is x = -4.
We have,
Distribute the -4 to the terms inside the parentheses:
9 - 4(2x - 1) = 45
9 - 8x + 4 = 45
Combine like terms:
13 - 8x = 45
Move the constant term to the other side of the equation by subtracting 13 from both sides:
13 - 8x - 13 = 45 - 13
-8x = 32
Divide both sides of the equation by -8 to isolate the variable:
(-8x) / (-8) = 32 / (-8)
x = -4
Therefore,
The solution to the equation 9 - 4(2x - 1) = 45 is x = -4.

x/8 = 3/4 solve for x
Answer: X= 6
Step-by-step explanation:
Answer:
x = 6
Step-by-step explanation:
Isolate the variable, x. Note the equal sign, what you do to one side, you do to the other.
First, multiply 8 to both sides:
(x/8)8 = (3/4)8
x = (3 * 8)/4
First, divide 8 with 4:
x = 3 * (8/4) = 3 * 2
Finally, simplify by multiplying:
x = 3 * 2
x = 6
x = 6 is your answer.

Solve:
-8(x - 3) + 5x < 9(x + 12)
This is Algebra 1
Answer:
The answer is x > -7
Step-by-step explanation:
The starting out equation is:
-8(x - 3) + 5x < 9(x + 12)
Once you've got your equation down, you have to remove the parentheses by doing distributive property, and multiplying the -8 by x and -3, [-8(x-3)] and the 9 by x and 12, [9(x + 12)]
Once you do that, you have something like this:
-8x + 24 + 5x < 9x + 108
Then you have to add like terms. That means adding -8x to the positive 5x, and only that since thats the only possible way.
-3x + 24 < 9x + 108
When that's over, you have to move the variable(in my case, 9x) to the left-hand side and change its sign:
-3x -9x + 24 < 108
You see that instead of positive 9x, like it was, it's now negative 9x since we changed its location.
And now do the same to the constant (in my case, 24) to the right-hand side. make sure to reverse its sign aswell, so now it's a negative 24. Now it looks a bit like this:
-3x -9x < 108 -24
Collect like terms (subtracting -9x by -3x, subtracting 108 by -24)
-12x < 84
Now that we isolated the variable, we have to divide it by -12.
KEEP IN MIND!!
When doing work like this, at some point you have to divide the variable by itself, and same thing to the other side. When the variable is a positive number and you're dividing by a positive number, DONT REVERSE THE GREATER/LESS (whatever you have) SIGN!!
When you are dividing by a negative number,
REVERSE THE SIGN!!
I always forgot this and got it wrong back then!!
Back to the lesson, itll look like this when dividing
-12x < 84
------ ------
-12x -12x
Once you divide it, you'll get this
x > -7
I hope this helped!

Solve
Answer:
Using the quadratic formula:
x = [-4 +- sqr root (16 - 4 * 1 * -1)] / 2 *1
x = [-4 +- sqr root (20)] / 2
x1 = [-4 + sqr root (20)] / 2
x2 = [-4 - sqr root (20)] / 2
x1 = 0.23607
x2 = -4.2361
Step-by-step explanation:
Answer:
x = - 2 ± [tex]\sqrt{5}[/tex]
Step-by-step explanation:
Given
g(x) = x² + 4x - 1
To solve for x let g(x) = 0, that is
x² + 4x - 1 = 0 ( add 1 to both sides )
x² + 4x = 1
Using the method of completing the square
add ( half the coefficient of the x- term )² to both sides
x² + 2(2)x + 4 = 1 + 4
(x + 2)² = 5 ( take the square root of both sides )
x + 2 = ± [tex]\sqrt{5}[/tex] ( subtract 2 from both sides )
x = - 2 ± [tex]\sqrt{5}[/tex]
Thus solutions in exact form are
x = - 2 - [tex]\sqrt{5}[/tex] , x = - 2 + [tex]\sqrt{5}[/tex]
