What is the factorization of the expression below?

25x^2 - 36

A. (5x+6)(5x-6)

B. (5x-6)(5x-6)

C. (5x- 4)(5x-9)

D. (5x + 4)(5x-9)

i think its D????????????????????????

5x5 = 25

9 x 4 = 36

- and a + equals a -

5x5 = 25

9 x 4 = 36

- and a + equals a -

Answer: The answer is A, (5x+6)(5x-6)

Step-by-step explanation: The negative and positive 6 will cancel out the regular X, meaning that 25x^2 and -36 are the only numbers left.

Sarah has $12.45 in quarters and nickels. She has 39 more nickels than quarters.

How many of each coin does she have?

**Answer:**

There are 14 nickes, 24 dimes and 48 quarters

**Step-by-step explanation:**

let x represent the number of nickels.

As she has 10 more dimes than nickels, the number of dimes is x + 10.

As she has twice as many quarters as dimes, the number of quarters is 2(x + 10)

the total value is $15.10, so I get an equation:

0.05x + 0.1*(x + 10) + 0.25*2(x + 10) = 15.10

0.05x + 0.1x + 1 + 0.5x + 5 = 15.10

0.65x = 9.1

x = 14

x + 10 = 24

2(x + 10) = 48

Slope 6, passing through (-4,2)￼￼￼

y=6x+26

y-y1=m(x-x1)

y-2=6(x-(-4))

y-2=6x+24

y=6x+24+2

y=6x+26

y-y1=m(x-x1)

y-2=6(x-(-4))

y-2=6x+24

y=6x+24+2

y=6x+26

Round 15.78947368 to two decimal

Places

Pls pls helppp

**Answer:**

= 15.79

**Step-by-step explanation:**

Find the number in the hundredth place (8) and look one place to the right for the rounding digit (9). Round up if this number is greater than or equal to 5 and round down if it is less than 5.

The given **number **i.e. 15.78947368 rounded to two **decimal **places is **15.79.**

Given that,

The givenBased on the above information, the **calculation **is as follows:

Here we have to check whether the **digit **is below 5 or above. If is above so the next **number **should be **rounded**.

Like 15.789

Here 8 is greater than 5

So for two decimals it is 15.79.

Therefore we can conclude that the given **number **i.e. 15.78947368 rounded to two **decimal **places is **15.79.**

Movie Mania requires customers to pay a sign-up fee of $20, and charges $4.00 to rent a DVD. Hurricane Video is free to join, but DVDs cost $6.00 to rent. Write and solve an equation to find the number of DVDs you would have to rent in order for both stores to charge the same. Explain what your variable represents.Movie Mania requires customers to pay a sign-up fee of $20, and charges $4.00 to rent a DVD. Hurricane Video is free to join, but DVDs cost $6.00 to rent. Write and solve an equation to find the number of DVDs you would have to rent in order for both stores to charge the same. Explain what your variable represents.

**Answer:**

10

**Step-by-step explanation:**

For movie mania:

Sign-up fee = $ 20

Rent for 1 DVD = $ 4.00

For Hurricane video:

Sign-up fee = 0

Rent of 1 DVD = $ 6.

Let [tex]n[/tex] be the number of DVDs to rent in order for both stores to charge the same.

For movie mania, charge to rent [tex]n[/tex] DVDs = Sign-up fee + rent of [tex]n[/tex] DVDs

=20+4n

For Hurricane movie, charge to rent [tex]n[/tex] DVDs = Sign-up fee + rent of [tex]n[/tex] DVDs

=0+6n=6n

Now, for both stores to charge the same, both the charges must be equal, we have

6n=20+4n

[tex]\Rightarrow 6n-4n=20[/tex]

[tex]\Righatarroe 2n=20[/tex]

[tex]\Rightarrow n =20/2=10[/tex]

Hence, the required number of DVDs to rent is 10 in order for both stores to charge the same.

-2(x -3) what number should be distributed

**Answer:**

-2

**Step-by-step explanation:**

-2 needs to be distributed to the rest of the equation so that gives you -2x+6

-2

-2 is on the outside of the parentheses, meaning it should be distributed to everything inside the parentheses

so, -2(x-3) is actually (-2x) + (-2 *-3)

-2 is on the outside of the parentheses, meaning it should be distributed to everything inside the parentheses

If 72 is 9 times larger than 8, which statement below is true?

A) 8 is 72 times larger than 9

B) 72 is 8 times larger than 9

C) 9 is 8 times larger than 72

D) 8 is 9 times larger than 72

B - because 72 is 9 times larger than 8. Therefore, 72 is also 8 times larger than 9. You can flip multiplication around just like addition.

If f(x) = 2x-5 and g(x) = x2 - 4x - 8, find (f+ g)(x).
