The regular price of a shirt is $15. Natalie bought it on sale for 0.9 times its regular price. Then the sale price was multiplied by 1.06 to include the tax.

Use the drop-down boxes to compare the regular price of the shirt to the sale price of the shirt
including tax.
The regular price of the shirt is $15. The sale price of the shirt before tax is
$10
.
The sale price of the shirt including tax is $
Choose...
. So, the sale price of the shirt
including tax is
Choose...
the regular price.

can someone answer this question plz

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
