Solve x^2 – 2x – 15 = 0 using the zero product property.
a. x = –5, 3
b. x = 7, –1
c. x = 5, –3
d. x = –3, –4

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

35x 3= 105

step-by-step explanation:

35+35= 70   70 + 35= 105
