Answer:

Step-by-step explanation:

4(3a-3)+2a when you expand youget

((4x3a)-(4x3)) + 2a = 12a - 12 + 2a then we collect the like term first 12a + 2a - 12

14a -12

therefore 14a - 12 is not equal to 14a- 3

12a-12+2a = 14a-3
14a-12 = 14a-3

So he’s not correct.

Hey there,

2w+10 would be the best choice here.

7. log(x+3)(2x + 3)+log(x+3)(x +5)= 2

OverLord2011 [107]

log(x+3)(2x+3)+log( x+3)( x+5) =2

logx(2x+3)+3(2x+3 )+log x(x+5)+3(x+5)

$log {2x}^{2} + 3x + 6x + 9 + logx {}^{2} + 5x + 3x + 15$

How do you write 75% as a fraction?

dem82 [27]

Answer:

3/4

Step-by-step explanation:

.74(75%) is equal to 75/100

The greatest common factor is 25, so divide 75 by 25 and 100 by 25.

75/25=3 100/25=4

So, 75/100 simplified is 3/4.
