Test help pls What is the value of the expression ((9 - 5)^2 – 1) + 3?
A) -5
B) 1
C) 5
D) 18

Answer 1

Answer:

D

Step-by-step explanation:

Here is what I did to arrive at my answer:

((9 - 5)^2 – 1) + 3

Use PEMDAS for this:

First, calculate what is in the parenthesis

(9-5)

  =4

and you are left with

4^2-1

Next is exponents...

4^2 = 4 · 4

    =16 - 1

Now substract

=15

Then add

15 + 3 = 18

There you have it! The answer is D, 18.

I hope this helps :)
