Evaluate (a-y)2(squared) +2y3(cubed), if a =2 and y=-3
A. -29
B. 43
C. 79
D. -53
I got answer choice A, am I correct?
heeellll naw! sike idk
To evaluate the expression (a-y)² + 2y³, substitute the given values of a and y into the equation.
Given: a = 2 and y = -3
Now, replace a with 2 and y with -3 in the equation:
(2 - (-3))² + 2(-3)³
Simplifying the expression inside the parentheses first:
(2 + 3)² + 2(-3)³
5² + 2(-3)³
Now, calculate the powers:
5² + 2(-27)
Simplify the multiplication:
25 + (-54)
Add the numbers:
25 - 54 = -29
Therefore, the answer is -29 (option A). So yes, you are correct.
