worth 30 points help plz given the equation ax + b = c ​, solve for x. Describe each statement in parts a to c below as​ always, sometimes, or never true. Explain your answer. a. If​ a, b, and c are whole​ numbers, x is a whole number. Choose the correct answer below. A. The statement is sometimes true because the solution could also be a fraction but not a negative number. B. The statement is never true because the solution involves​ division, meaning, x will be a fraction. C. The statement is sometimes true because the solution could also be a fraction or a negative number. D. The statement is always true. The solution for x is an expression involving​ addition, subtraction,​ multiplication, and/or​ division, and these operations always give whole numbers when​ a, b, and c are whole numbers.

(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
