Question

Can someone plz help me

Which of the expressions are equivalent to the one below? Check all that
apply.
(8 + 2) • 4 + 2

Answer 1

The answer is only D.

Explanation:

So let's look at this together:

Before we start anything, we MUST solve the equation that we are trying to find first. That way we can compare answers.

This is the problem we must solve using PEMDAS: (8 + 2) x 4 + 2 = 42 (USING PEMDAS)

Choice A:

8 x 4 + 2 + 2 =

We would need to use PEMDAS

P = Parenthesis

E = Exponents

M = Multiplication

D = Divison

A = Addition

S = Subtract

So for Choice A, we would go in order so starting with Parenthesis there is none, so we move on to Exponents. Since there is none we go to Multiplication. Now we Multiply 8 x 4 and get 32 and add 2 + 2. The sum doesn't add up to 42, so we know that the answer choice is wrong. If you keep doing this for all the answer choices, all of them would have a different number that wouldn't equal 42.

EXCEPT D. (8 x 4) + (2 x 4) + 2 = 42

HOPE THIS HELPS!

Answer 2

The answer is D. (8•4 ) + (2•4) + 2
