Answer:
Step-by-step explanation:
(7-98)(7+98)
= 7^2 - 98^2
= 49 - 9604
= -9555
translate each statement into mathematical language
length is nine inches less than twice width. L = 2W - 9
perimeter is 84 inches 2L +2W = 84
Substitute the expression for L (2W-9) for L in the second equation resulting in the follwing
2(2W-9) + 2W = 84
4W - 18 + 2W = 84
(4W+2W) = 84+18
6W = 102
W = 102/6 = 51/3
L = 2(51/3) - 9
= L= 17-9
L=6
Answer:
i think the answer is 1.33cm/s
Step-by-step explanation:
you have to use m=y2-y1/x2-x1
Answer: C) y=-2+2
Step-by-step explanation: Rise over run says that the slope is -2 and the line hits the y axis at +2 so the equation would be y = -2 + 2.
