Answer:

4. x = 11

5. x = -13

Step-by-step explanation:

4.   3x + 7 = 5x - 15

           -7           -7

3x = 5x - 22

-5x   -5x

-2x = -22

-2x/-2 = -22/-2

x = 11

5. 3(2x - 5) = 9x + 24

6x - 15 = 9x + 24

    +15          +15

6x = 9x + 39

-9x   -9x

-3x = 39

-3x/-3 = 39/-3

x = -13

Hope this helps, have a great day:)

One inlet pipe can fill an empty pool in 6 hours, and a drain can empty the pool in 12 hours. How long will it take the pipe to
Ainat [17]

Answer: 12 hours

Step-by-step explanation:

Let x = time it takes to fill the pool if the inlet pipe and drain pipe are both open

1/6 = portion of pool filled per hour by the inlet pipe

1/12 = portion of pool emptied per hour by the drain

1/x = portion of pool filled per hour if the inlet pipe and drain are both open

Then, 1/6 - 1/12 = 1/x

Multiply by the LCD, 12x, to obtain

2x - x = 12

x = 12 hours

Tomas factored the polynomial completely. What is true about his final product? 3x4−18x3+9x2−54x Ax(x2+B)(x+C)
iren2701 [21]

Answer:

A and B are both 3.  

Step-by-step explanation:

The given polynomial is 3x^4-18x^3+9x^2-54x.

We factor the GCF to obtain:

3x(x^3-6x^2+3x-18)

We factor further by grouping to get:

3x[x^2(x-6)+3(x-6)]

3x(x^2+3)(x-6)

We compare this to the given factored expression:

3x(x^2+3)(x-6)=Ax(x^2+B)(x+C)

We must have A=3,B=3, C=-6
