2/3
Step-by-step explanation:
Answer:
x=15
Step-by-step explanation:
The perimeter of a triangle has the formula 2l + 2w. Since the length is twice as long as the width, l = 2w. We use this equations to two possible perimeters, 90 and 120 feet.
P = 90 feet
90 = 2(2w) + 2w
90 = 6w
w = 15 feet
P = 120 feet
120 = 2(2w) + 2w
120 = 6w
w = 20
Thus, the range of w is from 15 to 20 feet. The answer is <span>15 ≤ w ≤ 20</span>
Answer:
x-5 = 0 has a remainder of 3
x = 5
therefore p(5) = 3
x+8 = 0 has a remainder of 0
x = -8
therefore p(-8) = 0
