Answer:

First equation = 3a + 9

= 3( a+3 )

Second equation = a²- 9

= a² - 3 ^ 2

= (a+3) (a-3)

Hence,

HCF = ( a+ 3)

Hope this helped

All the best !!

Round to the nearest hundreds place<br> Show your work<br> 4x = 7 - 8x - 27
faltersainse [42]

Answer:

x = 5

Step-by-step explanation:

4x = 7 - 8x - 27

1) Combine like terms (7 and -27). So, 7 + (-27) = -20.

        4x = 8x - 20

2) Subtract 8x from both sides of the equation. So, 4x - 8x = -4x.

        -4x = -20

3) Divide both sides by -4. So, -20 / -4 = 5.

        x = 5
