Answer:
a) -10
b) 2
Step-by-step explanation:
x=-2
y=3
so just substitute that in for each equation.
a)
(-2)2 + (-3)2 =
-2 x 2 = -4
( negative x negative = positive, positive x negative = negative, positive x positive = positive)
-3 x 2 = -6
-4 + -6 = -10
(think of subtraction as adding a negative number)
-10 is your answer
b) ((-2) + (3))2 =
solve the thing in parenthesis first (PEMDAS)
-2 + 3 = 1
now 1 is the parenthesis making the equation (1)2
1 x 2 = 2
2 is your answer
