Answer:
Step-by-step explanation:
The associative, commutative, and distributive properties of algebra are the properties most ... The Commutative Properties of Addition and Multiplication ... 14 + (−10) = 4 ... Note that y represents a real number. A) 5y • 2. B) 52y. C) 26 • 2 • y. D) y • 52 ... Here, the same problem is worked by grouping 5 and 6 first, 5 + 6 = 11.
Answer:
First "order of operations" mistake: step 2
First arithmetic mistake: step 4
Step-by-step explanation:
As we understand Rena's work, she wants to simplify ...

for x = -1 and y = 2.
Her work seems to be ...
<u>Step 1</u>

<u>Step 2</u>

<u>Step 3</u>

<u>Step 4</u>

_____
So, the first arithmetic error is in Step 4. However, the order of operations requires exponents be evaluated first. Doing that makes step 2 look like ...
