For questions 1 - 2, put the equation in the form ax2+bx+c = 0.
1. (x+2)2 = -X-2

x^2+6x+6=0

Step-by-step explanation:

(x+2)^2=-x-2

(x+2)(x+2)=-x-2

x^2+4x+4=-x-2

     +x   +2=+x+2

x^2+6x+6=0

x + y = 90 5x – 10y = 90 90 – 10y = 5x 90 + 10y = 5x

step-by-step explanation:

last month maria hiked the 5-mile mountain trail a number of times and she hiked the 10-mile canal trail several times. let x represent the number of times she hiked the 5-mile trail, and let y represent the number of times she hiked the 10-mile trail. if she hiked a total of 90 miles, which equation can be used to find the number of times maria hiked each trail? x + y = 90 5x – 10y = 90 90 – 10y = 5x 90 + 10y = 5x
