I think 51 because if you were to do it reverse then it would be 40x4=160 then -35-36-38 it would be 51.

Select an equation that is equivalent to a^2-144b^2 a) (a-12b)^2 B) (a+12b)^2 C) (a-12b)(a+12b) C) a^2-24ab+144b^2
Nataliya [291]

Answer:

C) (a-12b)(a+12b)

Step-by-step explanation:

a^2-144b^2 = (a-12b)(a+12b)

This is the formula that when two terms squared are written with a minus sign between them their factors are the product of the original numbers once with a plus sign and once with the minus sign.

This can be explained by multiplying them.

                (a-12b)

<u>                 *(a+12b)         </u>

                  a²- 12ab

  <u>                     +12ab - 144b²      </u>

<u>                     a²    +0    - 144b²    </u>

We see we get the same answer as applying the formula above.
