<span>You have studied polynomials consisting of constants and/or variables combined by addition or subtraction. The variables may include exponents. The examples so far have been limited to expressions such as 5x<span>4 </span>+ 3x<span>3 </span>– 6x<span>2 </span>+ 2x containing one variable<span>, </span>but polynomials can also contain multiple variables. An example of a polynomial with two variables is 4x2y – 2xy2 + x – 7.</span>
Many formulas are polynomials <span>with more than one variable, such as the formula for the surface area of a rectangular prism: 2<span>ab </span>+ 2bc + 2ac, where <span>a, b, </span>and <span>c </span>are the lengths of the three sides. By substituting in the values of the lengths, you can determine the value of the surface area. </span>By applying the same principles for polynomials with one variable, you can evaluate or combine like terms in polynomials with more than one variable<span>.</span>

Answer:
r=4
Step-by-step explanation:
-4 (r+2) =4 (2-2r)
Divide each side by 4
-4/4 (r+2) =4/4 (2-2r)
-(r+2) = (2-2r)
Distribute
-r-2 = 2-2r
Add 2r to each side
-r+2r -2 = 2-2r+2r
r-2 =2
Add 2 to each side
r-2+2 =2+2
r=4
Check
-4 (r+2) =4 (2-2r)
-4 (4+2) =4(2-2*4)
-4(6) =4(2-8)
-24 = 4(-6)
-24 = -24
This checks
