Answer:
r=4
Step-by-step explanation:
Let's solve your equation step-by-step.
−4(r+2)=4(2−2r)
Step 1: Simplify both sides of the equation.
−4(r+2)=4(2−2r)
(−4)(r)+(−4)(2)=(4)(2)+(4)(−2r)(Distribute)
−4r+−8=8+−8r
−4r−8=−8r+8
Step 2: Add 8r to both sides.
−4r−8+8r=−8r+8+8r
4r−8=8
Step 3: Add 8 to both sides.
4r−8+8=8+8
4r=16
Step 4: Divide both sides by 4.
4r
4

r=4
Answer:
r=4
C. 9:5
Because 36:20 keep simplifying it down and you will come out to 9:5
You plug 11 in where x is.
r(11) = (11 + 1)(11 - 3)
= (12)(8)
= 96
