Which expressions are equivalent to 4(-52 + 2) + (-6) ?
choose all answers that apply:
203 - 2
2-102 + 1)
none of the above

None of the above is the correct answer.
4(-52+2)= -208+8, which equals -200.
-200+-6=-206

None if the above

Let’s start by rewriting the equation

4(-52+2)+(-6)

We’re going to solve this using the PEMDAS method

P-parentheses
E-exponents
M-multiplication
D-division
A-addition
S-subtraction

The first step here is parentheses. That means we need to solve what is in parentheses first. That is (-52+2). Let’s do this now.

4(-52+2)+(-6)

4(-50)+(-6)

In this, +(-6) is the same thing as writing -6. Let’s fix this now.

4(-50)+(-6)

4(-50)-6

The next step here according to PEMDAS is multiplication. The multiplication we see here is 4 and -50. Let’s multiply this now.

4(-50)-6

-200-6

Finally, let’s add -200 and -6

-200-6

-206
