Robert weighs 20 pounds more than his friend Genesis. The sum of their weights is more than 220 lbs. What is are the smallest possible weights for each of them?

robert=120lbs,genesis=100

Step-by-step explanation:take genesis as (x) and since robert is 20 pounds heavier he would be (X+20) so:

x+(x+20)  =220lbs

2x+20=220

2x=220-20

2x=200

x=100 which we took as genesis

which leaves robert's weight 100 +20 =120

answer:   x = 3 + √11     and     x = 3 - √11

step-by-step explanation:

x² - 6x + 9 = 11

(x - 3)² = 11

x - 3 = ±√11

    x = 3 ± √11

x = 3 + √11     and     x = 3 - √11
