Find the sides of a rectangle whose area is given as x2 +15x +56.
x^2 + 15x + 56
Good way to factor quadratic functions:
In a function x^2 +bx + c
Find two number that when multiplied together will form c (in our case 56) and that when added together form b (in our case 15)
Number 1 x Number 2 = 56
Number 1 + Number 2 = 15
Number 1 = 8
Number 2 = 7
(It'll be easier to find these numbers with practice)
Now in the function instead of bx, split it and use (number 1)x + (number 2)x
It's allowed because it's the same value since N1 + N2 = bx already
x^2 + 15x + 56
Now is:
x^2 + 8x + 7x + 56
Now you can factor this function much easily because it can transformed into:
(x + 8)(x) + (x + 8)(7)
x + 8 is the common factor
it can become:
(x + 8) (x + 7)
The sides of the rectangle are 8 and 7
Hope this helps you with factoring :)
There is a bag filled with 3 blue and 5 red marbles.
A marble is taken at random from the bag, the colour is noted and then it is not replaced.
Another marble is taken at random.
What is the probability of getting 2 reds?
Answer:
5/14Step-by-step explanation:
There are 5 red marbles out of 8.
The probability of the first red:

Answer:
sending love to you that work is hard
Answer:
Assuming that the multiplicities of the five aforementioned roots ( {0, 5, 1, 3i, -3i} ) are each 1, the 6th zero can be any real number.
Step-by-step explanation:
Because P(X) has real coefficients, and 3i is a zero, we conclude that -3i is also a zero of P(X). Assuming that the multiplicities of the five aforementioned roots ( {0, 5, 1, 3i, -3i} ) are each 1, the 6th zero can be any real number.

Answer:
pretty sure it's 10 1/2
Answer:
I think the answer is D. 12 1/2
Step-by-step explanation:
If you add up the two thing it becomes: 15 cups of flour and 6 cups of milk. So if you divide 15 by 6, it's 2.5. Now all you have to do is 5 (since there are 5 cups of milk) times 2.5, and you get 12.5. And 12.5 is 12 1/2 in fraction form. Hence, the answer is D. 12 1/2.

Find the area of this figure. Round your answer to the nearest hundredth. Use 3.14 to approximate
Step-by-step explanation:
Area of a Triangle:
bh/2
8 ft is the given height
6 ft is the given base (or width)
(8)(6)/2
48/2
= 24 ft²
In addition to this, we will have to find the area of the semicircle.
Area of a Semicircle:
πr²/2
The question tells us to use 3.14 in place of π.
3.14r²/2
The diameter is 8 ft as it is given to us in the diagram, but in the formula we would have use the radius, and because the radius ia half of the diameter we will divide 8 by 2.
8/2
= 4
3.14(4)²/2
Solve...
3.14(16)/2
50.24/2
= 25.12 ft²
Now that we have found the area of both the triangle and the semicircle, we can add them together to find the area of the figure.
24 ft² + 25.12 ft²
= 49.12 ft²
Our final answer is A=49.12 ft² because it is already in the hundredths place.

What is the equation written in vertex form of a parabola with a vertex of (9, -1) that passes through (7. 7)?
O
A. y = 2(x - 992 - 1
B. y = 2(x + 1)2 - 9
O C. y = 2(x - 7)2 + 7
D. y = 7(x - 9)2 - 1
Answer:
[tex]y = 2\, (x - 9)^{2} - 1[/tex].
Step-by-step explanation:
If the vertex of a parabola is [tex](h,\, k)[/tex], there would exist a constant [tex]a[/tex] ([tex]a \ne 0[/tex]) such that the following would be an equation for this parabola:
[tex]y = a\, (x - h)^{2} + k[/tex].
The equation above is in the vertex form.
In this question, the vertex of this parabola is [tex](9,\, -1)[/tex]. (Such that [tex]h = 9[/tex] and [tex]k = -1[/tex].) Therefore, the equation of this parabola in the vertex form would be:
[tex]\text{$y = a\, (x - 9)^{2} + (-1)$ for some $a \ne 0$}[/tex].
It was also given that the point [tex](7,\, 7)[/tex] is on the parabola. In other words, if [tex]x = 7[/tex] and [tex]y = 7[/tex], the equation of this parabola ([tex]\text{$y = a\, (x - 9)^{2} + (-1)$}[/tex]) should be satisfied. In other words:
[tex]7= a\, (7 - 9)^{2} + (-1)[/tex].
Solve this equation for [tex]a[/tex].
[tex]a = 2[/tex].
Therefore, the equation of this parabola in vertex form would be[tex]y = 2\, (x - 9) + (-1)[/tex], which is equivalently [tex]y = 2\, (x - 9)^{2} - 1[/tex].

Step-by-step explanation:
Using the method of completing the square, rewrite x² – 14x in the form (x + b)2 +c.
x2 – 14x = x(x - 14)
x² – 14x =
If you want to have
[tex]x^2-14x = (x+b)^2+c[/tex]
notice that expanding the right side gives
[tex]x^2-14x = x^2+2bx+b^2+c[/tex]
so that
[tex]\begin{cases}2b=-14 \\ b^2+c=0\end{cases}[/tex]
It follows that b = -7 and c = -49. Then
[tex]x^2-14x = \boxed{(x-7)^2-49}[/tex]

Question
Find the equation of the line with slope m
=
2 that contains the point (8,19).
Answer: y= 2x + 3
Step-by-step explanation:
Point slope formula: y = mx + b
Since the given point is (8,19), 19 is our y, and 8 is our x. Since the slope is 2, our m is 2.
Sub in values.
y = mx + b
19 = 2(8) +b
19 = 16 + b
b = 19-16
b = 3
Now that we have m and b, we can make the equation.
y = mx + b, sub in 2 for m and 2 for b
y = 2x + 3
19 = 2(8) + 3
19 = 16 + 3
19 = 19
So the answer is y = 2x+3

Evaluate 6 to the power of negative 2
A. -1/36
B. -12
C. -36
D. 1/36
Answer:
Positive 1 over 6 raised to the 2nd power 1/62 or 1 over 36 which is 1/36. To find -6-2, take the inverse of -62.
(first find -62) -62 = -6 * -6 = 36
(then take the inverse of 36, which is 1 over 36) = 1 / 36 = 0.0277
so, -6-2 =0.0277

Step-by-step explanation:
Use the given information to write an equation and solve the problem.
(28-31 in the picture)
Answer:
28. 120 degrees
29. 30 degrees
30. 56 degrees & 124 degrees
31. 72 degrees, 108 degrees, and 18 degrees
Step-by-step explanation:
We assign variable x for the answer we are looking for (28-29).
28.
Supplement means x + y = 180 degrees. We also know x = 2y. Substitution gives us 3y = 180 degrees, so y = 60 degrees and x = 120 degrees.
29.
Complement means x + y = 90 degrees. We are given 2x = y. Substitution brings us 3x = 90 degrees, x = 30 degrees.
30.
Supplement means x + y = 180 degrees. We are told that y = 2x + 12, so we substitute. This gives 3x + 12 = 180 degrees, x = 56 degrees. Substituting that back into the equation for y, we get 124 degrees.
31.
Supplement means x + y = 180 degrees. Complement means x + z = 90 degrees. Using our given info, we know y = 6z. We can substitute that in to get x + 6z = 180. Subtracting our second and third equations, we get 5z = 90, z = 18 degrees. Therefore, x = 72 degrees, y = 108 degrees.
