Question

Help me, please... :(

Answer 1

“A.”

Explanation:

15 + 3x is the equation, so we need to have the 3 multiplying by “x” no matter what.

Answer “A.” 3(5+x) would give us 15+3x when the 3 is distributed to the 5 and the “x”

You are welcome :D

Answer 2

[A] 3(5+x)

Explanation:

To Find which expression is equivalent to 15 + 3x

We can simplify to see:

Start with [A] 3 ( 5 + x )

3 · x = 3x

3 · 5 = 15

3x + 15

True

Next we have [B] 5 ( 3 + x)

5 · x = 5x

5 · 3 = 15

5x + 15

False

Then we have [C] 3 ( 5 + 3x)

3 · 3x = 9x

3 · 5 = 15

9x + 15

False

Finally, we have [D] 5 ( 3 + 3x)

5 · 3x = 15x

5 · 3 = 15

15x + 15

False

3x+15 is the same thing as in 15 + 3x

Thus, [A] 3 ( 5 + x) is the correct answer.
