What is the value of x in the equation 2.5-0.25x=-3?
7-22
o 1 1
o 22

22

Step-by-step explanation:

Subtract 2.5 to -3 to get -5.5 and then divide that to -0.25 to get 22.

-7

step-by-step explanation:

x^2 + 18x + 74 = (x + 9)^2 - 81 + 74

= (x + 9)^2 - 7.

so q = -7.

because linear equations are a lot simpler than quadratics equations, and linear equations formula is a lot easier to memorize. that's why i think they're harder.
