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

the answer for this question is : 360°

step-by-step explanation:

we have been given a triangle   we need to tell which one of these is a triangle below to map onto itself.

360° rotation is the complete rotation which eventually leads to the same figure which is given.

the correct will be, that is 360° that will cause the triangle below to map onto itself.
