Answer:
38.5 = x
Step-by-step explanation:
9/ (x+2) = 2/9
Using cross products
9*9= 2(x+2)
Distribute
81 = 2x+4
Subtract 4 from each side
81-4 = 2x+4-4
77= 2x
Divide each side by 2
77/2 = 2x/2
38.5 = x

Step-by-step explanation:
Answer:
When I squared the binomials, they became quadratic trinomials.
(Not sure if this is the kind of answer you want, sorry if it's not!)
(x-3)² = x² - 6x + 9
(x+2)² = x² + 4x + 4
(x-4)² = x² - 8x + 16
(x+5)² = x² + 10x + 25
