Question

Which of the following number sentences is true?

A. 40 -2 × 3² = 4
C. 40 -2 × 3² = 114

B. 40-2 × 3² = 22
D. 40 -2 × 3² = 360

Answer 1

B is true .22 is the real answer

Answer 2

B

Explanation:

First, we compute the exponent (3² = 9).

Next, we compute the multiplication and division (from left to right), so we have (40 - 2 × 9) = (40 - 18) = 22.

Thus, the number sentence 40 -2 × 3² = 22 is true.
