Determine whether each expression is equivalent to (10 x 18) + (10 x s).

Choose Yes or No for each expression.
A 190 x s. Yes or no
B 20 x 18s. Yes or no
C 180 + 10s. Yes or no
D(10 + 10) x (18+ 8). Yes or no
E 10(18+ s). Yes or no

Answer 1

I assume the "x" represents multiplication?

Answer:

no, no, yes, no, yes

Explanation:

(10•18)+(10•s)

180+10s

First Parentheses: how to simplify

Second Parentheses: why yes/no

A: 190s (different expression)

B: 360s (multiply)(different expression)

C: 180+10s (same expression)

D: 100(16)=1600 (multiply)(no variable)

E: 180+10s (distribute the 10)(same expression)
