Herny brought a new television for $2,688 using the store's finance plan . he will pay $112 a month for 24months. write an equation Orvis could use to find out how much money he still owe after each month plan

  owed = 2688 -112n

Step-by-step explanation:

After n months, there are 24-n payments left. The amount of each payment is $112, so the amount remaining to be paid is ...

  owed = 112(24 -n) . . . . dollars

This can be simplified to ...

  owed = 2688 -112n

32

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
