Factor completely
4x^2 - 18x - 36

Answers

Answer 1

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

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)

Point M is on line segment LN. Given LN = 9, MN = 4x, and LM=5x
determine the numerical length of MN

Answer : MN =

Answers

Answer:

MN = 4

Step-by-step explanation:

Given that L, M, N are collinear,

LN = 9,

MN = 4x

LM = 5x

Required:

Length of MN

SOLUTION:

To calculate the numerical length of MN, we need to find the value of x.

To find the value of x, generate an equation to solve for x as follows:

[tex] LM + MN = LN [/tex] (segment addition postulate)

[tex] 5x + 4x = 9 [/tex] (substitution)

Solve for x

[tex] 9x = 9 [/tex]

Divide both sides by 9

[tex] \frac{9x}{9} = \frac{9}{9} [/tex]

[tex] x = 1 [/tex]

MN = 4x

plug in the value of x

MN = 4(1) = 4

Multiply both sides by 3/2.

[tex]\dfrac{3}{2} \times \dfrac{2}{3}(x - 18y) = \dfrac{3}{2} \times 6y[/tex]

[tex]x - 18y = 9y[/tex]

Add 18y to both sides.

The bells are adding a new room to their house. The room will be a cube with volume of 4,913 feet cubed. They are going to put in hardwood floors, and the contractor charged $5 per square foot. How much will the j hardwood floors cost?

Answers

Answer:

  $1445

Step-by-step explanation:

The side length of the room is the cube root of the volume of the cube:

  s = ∛4913 = 17 . . . . feet

The area of the floor is the square of this side length:

  A = (17 ft)² = 289 ft²

The cost of the floor is $5 for each square foot:

  cost = ($5/ft²)(289 ft²) = $1445

The hardwood floor will cost $1445.

Step-by-step explanation:

Makes it a bit easier if you convert to 24 hr time.

11. 10 - 19 is 9hrs

12. 545-1120 is 11-5 20-45 -> 6hrs -25min -> 5hrs 35min

13. 1800 - 2148 is 21-18 48-00 -> 3hrs 48 min

Answer:

11. 9h

12. 5h 35 min

13. 3h 48min

Step-by-step explanation:

11.

here,

time elapsed = ∆t = final time - initial time

= 7 pm - 10 am

= (12+7) h - 10 h {turn pm into am by adding 12 and converting both into hour and min}

= 9 h

12.

similarly,

time elapsed = ∆t = final time - initial time

= 11 h 20 min - 5 h 45 min

= 5 h 35 min

13.

similarly,

time elapsed = ∆t = final time - initial time

= 9 h 48min - 6 h

= 3h 58min

The coordinates of point T are (0,2). The midpoint of ST is (7, -4). Find the coordinates of point S.

Answer: The coordinates of point S is (14,-10).

Step-by-step explanation:

[tex](x,y)=(\dfrac{x_1+x_2}{2},\dfrac{y_1+y_2}{2})[/tex]

Given, The coordinates of point T are (0,2). The midpoint of ST is (7, -4).

Let (a,b) be the coordinates of point S.

Then,

[tex](7,-4)=(\dfrac{0+a}{2},\dfrac{2+b}{2})\\\\\Rightarrow\ 7=\dfrac{a}{2},\ \ \ -4=\dfrac{2+b}{2}\\\\\Rightarrow\ a=7\times 2= 14, \ \ 2+b= 2\times-4 =-8\\\\\Rightarrow\ a=14,\ \ \ 2+b=-8\\\\\Rightarrow\ a=14, \ b= -8-2=6--10\\\\\Rightarrow\ a=14,\ b=-10[/tex]

Hence, the coordinates of point S is (14,-10).

Perform the indicated operation. 1 and 2/3 plus 5 and 3/8

Answers

Answer:

7  1/24

Step-by-step explanation:

1 2/3+5 3/8=?

first you need to find the least common multiple between 2/3 and 3/8.

the lcm would be 24, so 24 would be your new denominator for both fractions, but the numerators will change to how much you just multiplied each denominator by to get 24. 8x3 is 24, so you would multiply 3x3 to get the new numerator: 9. 3x8 is 24, so you multiply 2x8 to get the new numerator for that fraction:16.

so your new fractions are 1 16/24 + 5 9/24

now you add 16+9=25 (25/24, which becomes 1  1/24), so then you have another whole number: +1, and you add it to 5+1, so no it's 5+1+1=7

so the answer would be 7 1/24

No, it is not. We know ordered pairs go like this: (x, y). If x is equal to 6.5, then we can do 6.5 + 4.5, which equals 11. If x is 6.5, then y should be 11, not 2.
