The linear function that is represented by which table has the same slope as the graph? a(x y -25 -9 -21 -7 -17 -5 -13 -3 -9 -1 b(x y -25 9 -21 7 -17 5 -13 3 -9 1 c(x y -9 -12 -7 -21 -5 -17 -3 -13 -1 -9 d(x y 1 -9 3 -13 5 -17 7 -21 9 -25

idk lol

step-by-step explanation:

26?

step-by-step explanation:

(b) 240

step-by-step explanation:

first, we use the pythagorean formula using the given side lengths to find x. then we use x to find the side lengths. then we add the side lengths to find the perimeter.

pythagorean theorem formula:

a^2 + b^2 = c^2

(x - 20)^2 + (x - 40)^2 = x^2

x^2 - 40x + 400 + x^2 - 80x + 1600 = x^2

x^2 -120x + 2000 = 0

(x - 100)(x - 20) = 0

x - 100 = 0 or x - 20 = 0

x = 100 or x = 20

we see that the solution x = 20 must be discarded because it will give a negative side length and a side length of 0. the only valid solution is x = 100.

perimeter = sum of the lengths of the sides

perimeter = x + x - 20 + x - 40

perimeter = 3x - 60

replace x with 100.

perimeter = 3(100) - 60

perimeter = 300 - 60

perimeter = 240

6e14 is the answer.
