When multiplying two numbers, a person can mentally add one of those numbers the other number amount of times.
The correct answer to this problem is be because you have to multiply the 4 outside of the parentheses with the 4 inside of the parentheses which gives you 16X and then afterwards you have to do the same with the 6 with so since 4•6=24 you can automatically eliminate answer choice D and then you add up your 3x to your 16x which will be 19x so it would be B. 19x+24
They didn’t distribute the -1 (which is the “-”) correctly into the numbers in the parentheses. After distributing correctly, step 1 should be
8a+3+5a-2a
