Hello from MrBillDoesMath!

Answer:

Your friend is incorrect


Discussion:

| 3x + 8 | -9  = -5           =>    ( add 9 to both sides)

| 3x + 8 |  -9 + 9 = -5 + 9 =>

| 3x + 8 |  = 4 =>

3x +8 = 4  or  3x + 8 = -4 =>

x = -4/3    or   x = -4



Thank you,

MrB

Gnom [1K]

Answer: First Choice. 5²*x

Step-by-step explanation:

<u>Definition:</u>

When a number is squared in math, it means it's been multiplied by itself. There would be a (2) signifier as a subscript on the number.

Times in mathematics stands for multiplied by.

<u>Solve:</u>

" Five Squared Times Four"

Five = 5

Squared = ²

Times = ×

Four = 4

Finally, combined together will be:

  • 5² · x

Hope this helps!! :)
