Question

What is the solution to Mr. Smith's equation?

Answer 1

C 39

Explanation:

(16 - 2w)² + (3y ÷ 3z)

(16 - 2w)² + (y ÷ z)

[16 - 2(5)]² + (9 ÷ 3)

[16 - 10]² + (9 ÷ 3)

6² + 3

36 + 3

39

Answer 2

39

Explanation:

(16-2w)^2 + (3y÷3z)

Let w=5 y=9 and z=3

(16-2*5)^2 + (3*9÷3*3)

PEMDAS says parentheses first

Multiply and divide in the parentheses

(16-10)^2 + (27÷9)

Then add and subtract in the parentheses

(6)^2 + (3)

Now the exponent

36 +3
