Question

may someone help me with this question? Thank you!

Answer 1

3x3x= 9x
3x5= 15
the answer is 9x+15
because the parentheses mean to multiply

Answer 2

$\qquad\qquad\huge\underline{{\sf Answer}}$

Let's solve ~

$\qquad \sf  \dashrightarrow \:3(3x + 5)$

now plug in the value of x as 5

$\qquad \sf  \dashrightarrow \:3(3(5) + 5)$

$\qquad \sf  \dashrightarrow \:3(15 + 5)$

$\qquad \sf  \dashrightarrow \:3(20)$

$\qquad \sf  \dashrightarrow \:60 \:$

So, the equivalent value is 60
