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
