Answer:   4p + 18q - 5m - 6 + 7m²

<u>Step-by-step explanation:</u>

(4p + 2q) - (2m - 7q + 5) + (7m² - 3m + 9q - 1)

distribute the negative sign:

4p + 2q - 2m + 7q - 5 + 7m² - 3m + 9q - 1

group the like terms:

4p + (2q + 7q + 9q) + (-2m - 3m) + (-5 - 1) + 7m²

combine like terms:

4p + 18q - 5m - 6 + 7m²

Answer:

Not quite sure what you're meant to solve for, but my solution is below.

Step-by-step explanation:

The square root of a value squared is the absolute value of that value, because squaring removes all negatives. Therefore:

\sqrt{(y+2)^2}=c

\mid y+2\mid=c

\mid y\mid =c-2

Hope this helps!

Step-by-step explanation:

-4x + 3 < 23

-4x < 20

x > -5

hmm,I don't think we need to put equal sign instead of (<) , for when we started calculating.

we can just keep the question as it is and calculate.
