Question

Where can we put parentheses in 4•7+2 to make it equivalent to 36?

Answer 1

Answer:

A

Step-by-step explanation:

The simpler way to calculate this question is just to calculate A and B

A - 4 x (7+2) = 4 x 9 = 36

B - (4 x 7) + 2 = 28 + 2 = 30

A = 36

=> Thus, our answer is A

Hope this helps!

Answer 2

Answer:

A. 4 * (7+2)

Step-by-step explanation:

Let's evaluate choice A and B. Solve each expression according to PEMDAS: Parentheses, Exponents, Multiplication, Division, Addition, Subtraction.

The option that equals 36 will be the correct choice.

A.

4 * (7+2)

Solve the parentheses first. Add 7 and 2.

4 * (9)

Multiply 4 and 9.

36

B.

(4*7)+2

Solve the parentheses first. Multiply 4 and 7.

(28)+2

Add 28 and 2.

30

When evaluated, choice A equals 36. Therefore, A is correct. When the parentheses are arranged like so: 4 * (7+2) it will be equivalent to 36.
