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

Answer:
r=4
Answer:
x = 5
x = 0.5
Step-by-step explanation:
2x2 - 11x + 5 = 0
Roots: 5, 0.5
Root Pair: 11/4 ± 9/4
Factored: f(x) = 2(x - 5)(x - 0.5)
I am pretty sure that the median is 80, correct me if I'm wrong :)
