Answer:
18
Step-by-step explanation:
Substitute x = - 3 into the expression
2x²
= 2(- 3)²
= 2 × 9
= 18
First, solve the parenthesis
-8 + 6 = -2
-3[5 - (-2)]
Note that two negatives = one positive
-3[5 - (-2)] = -3[5 + 2]
Simplify. Solve the bracket
-3[5 + 2] = -3[8]
Simplify. Multiply to get the answer
-3 x 8 = -24
-24 is your answer
hope this helps
