Question

Find the measure of x:
Find the measures of QR:

Answer 1

`x=4\ units\\QR=15\ units`

Explanation:

Rectangles

It's a geometric shape with 4 straight sides with all interior angles of 90° and opposite sides parallel and of equal lengths. The given shape shows a rectagle whose opposite sides must be eaual, thus

`-1+4x=3x+3`

Rearranging

`4x-3x=3+1`

`\boxed{x=4\ units}`

The measure of QR is

-1+4x which is the same as 3x+3, thus

`QR=3x+3=3(4)+3=15\ units`

`\boxed{QR=15\ units}`
