Find the value of the expresstion. a^2 y + a^3 for a = -1.5 abd y= -8.5

  -22.5

Step-by-step explanation:

Put the numbers in place of the variables and do the arithmetic. This might be easier of you factor the expression first. Your calculator can do this evaluation.

  a^2y +a^3 = a^2(y +a)

  = (-1.5)^2(-8.5 -1.5) = 2.25(-10) = -22.5

1.-3, 2.1/3=3
