We are given the following equation:

a^2+17=42

Subtract both sides by 17

a^2=25

Take the positive/negative square root of both sides

a=\pm5

This should be your answer. Let me know if you have any questions, thanks!

Simplify the expression using the distributive property.
Ede4ka [16]

Answer:

-9x - 14

Step-by-step explanation:

Distribute (multiply) the 1/4 to everything in the parentheses.

1/4 * 4x = 1x or x       1/4 * -8 = -2

Then you distribute (multiply) the -2 to everything in the parentheses.

-2 * 5x  = -10x       -2 * 6 = -12

Then you put the equations together.

x - 2 - 10x - 12

Then you combine like terms.

x - 10x = -9x      -2 - 12 = -14

Finally you get your answer in simplest form.

-9x - 14
