4(x+2) = 4·x + 4·2 = 4x + 8
3(x+7) = 3·x + 3·7 = 3x + 21
5(2x+7) = 5·2x + 5·7 = 10x + 35

Answer:
-720
Step-by-step explanation:
We are given the expression:

and asked to evaluate when x= -2 and y= -3.
Therefore, we must substitute -2 for x and -3 for y.

Solve according to PEMDAS: Parentheses, Exponents, Multiplication, Division, Addition, Subtraction.
Evaluate the first exponent.
⇒ (-2)³ = -2 * -2 * -2= 4*-2= -8

Evaluate the second exponent.
⇒ (-3)²= -3 * -3= 9

Multiply 10 and -8.

Multiply -80 and 9.

The value of 10x³y² at x= -2 and y= -3 is -720
