Paolo wrote the following equation for the perimeter of a rectangle.

p=2(l+w)

a. w=p-21
b. w=p-1
c. w=p-21/2
d. w=p+21/2

The answer is the option C

Step-by-step explanation:

we know that

The perimeter of a rectangle is equal to

where

L ---->  is the length side of rectangle

W ----> is the width side of the rectangle

Solve for W

That means -------> isolate the variable W

Divide by both sides

Subtract both sides

step-by-step explanation:

i found the koficent of the linear function and i foun c acordind to the strict formula y=kx+c and then i took 2 as an x and replacet it on the formula i found and then foun the y

step-by-step explanation :

we know that

the measurement of the outer angle is the semi-difference of the arcs which comprises

in this problem

m< xzy is the outer angle

substitute the values

the measure of angle xoy is equal to

> by central angle

substitute the value
