Ok it’s either A or D I don’t remember but I need help Brice has twice as many stamps in his collection as his
friends Anthony and Paul combined. Paul has 32 stamps
in his collection. Brice has 96 stamps in his collection.
How many stamps does Anthony have in his collection?

The equation 2(x + 32) = 96 models this situation. Which choice shows the
sequence of operations needed to solve this problem, using both arithmetic
and algebra?

answer:   y=2x-3

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

here's a poem i finished a while ago. i hope you like it and that it inspires you.
