The volume of a small packing box is "3x^2 + 3x" in^3 smaller than a large packing box with a volume of "5x^2 − 2x + 10" in^3. find a single expression that represents the size of a small packing box.

a) 2x2 − 2x + 10

b) 2x2 − 5x + 10

c) 8x2 − 5x + 10

d) 8x2 + x + 10

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

answer:   x = 3 + √11     and     x = 3 - √11

step-by-step explanation:

x² - 6x + 9 = 11

(x - 3)² = 11

x - 3 = ±√11

    x = 3 ± √11

x = 3 + √11     and     x = 3 - √11

x= 3^y
