Hey there! :)
Answer:
A. 23.
Step-by-step explanation:
Given:
5 + 2(x + 7)² for x = -4
Substitute in -4 for x in the equation:
5 + 2((-4) + 7)²
5 + 2(3)²
5 + 2(9)
5 + 18 = 23.
Therefore, the correct answer is A. 23.
This is assuming that the question laid out the sequence of a calculation.
4y x 3y + z = 100
12y^2 + z = 100
17.94 You are multiplying 4.6 x 0.9
