A rectangle had a length of x and a width of 3x^3 + 2 - x^2. find the perimeter of the rectangle when the length is 8 feet. The polynomial that models the perimeter of the rectangle is

The perimeter is feet

a; x = 0.5

step-by-step explanation:

-10x = -5

x = 0.5

the simplified form is

step-by-step explanation:

we want to simplify the expression,

let us change the middle bar to a normal division sign to obtain,

we multiply the first fraction by the reciprocal of the second fraction to obtain,

we factor to obtain,

we cancel the common factors to get,

we simplify to get,

the correct answer is b

180-142=38 for the acute angle next to the entry

90+38=128

180-128=52

a=52
