A)PQR
B)QRT
C)RST
If PQ=3x+4 and the perimeter to PQR=57, find the value of x

-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.

answer: its c because when it has a magnet next to it it will move away from the mixture. hope this
