Ineed with first two in blue! thx: )

11.) 3² - 4y

3² - 4(2) = 9 - 8 = 1

12.) 9x - 2³

9(2) - 2³ = 18 - 8 = 10

for this case we have the following expression:

to solve, we rewrite the expression as:

we apply double c and we have:

thus, the quotient is 48.

so, patel found a wrong ratio and the multiplication was incorrect.

option d
