Solve for 2. Write the smaller solution first, and the larger solution s
4x2 + 40 + 84 = 0
smaller x =
larger x =

4(x^2 +10 +21)

4(x+3)(x+7) = 0

Smaller

4(x+7) = 0

4x +28 = 0

4x = -28

x = -28/4

x = -7

Larger

4(x+3) = 0

4x + 12 = 0

4x =-12

x = -12 / 4

x = -3

Step-by-step explanation:

15 units use socratic

step-by-step explanation: 15 units

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
