The length of a rectangle in terms of x is x + 8, and its width is 2x + 3. What is the perimeter of this rectangle?

59

Step-by-step explanation:

value in a expansion is 5

expansion

simplistic form

x = 25

step-by-step explanation:

a^2+b^2=c^2

7^2+24^2=c^2

49+576=625

sqrt625=25

x=25

f(x) has value 150 at x= 0

and 0 at x= 3

so d(f(x))/dt = slope = -150/3 = -50
