The length of a rectangle is 2 km less than 3 times the width. if the perimeter is 68 km, what is the length of the rectangle

The length of the rectangle is 25 km

Step-by-step explanation:

Let

x ----> the length of rectangle

y ----> the width of rectangle

we know that

The perimeter of rectangle is

we have

so

simplify

---- > equation A

---> equation B

substitute equation B in equation A and solve for y

Find the value of x

therefore

The length of the rectangle is 25 km

n

step-by-step explanation:

(f - g)(x) = 5x^3 - 3

step-by-step explanation:

rearrange these functions vertically, with like terms in separate columns:

f(x) = 5x^3 - 2

g(x) =         +1

now subtract, column by column:

(f - g)(x) = 5x^3 - 3
