take both of sides paranthesis square
(2a+7b)^2=(11)^2
4a^2+2.4a.7b+49b^2=121
4a^2+49b^2+56.2=121
4a^2+49b^2=9
Answer:
x = 13 1/2 days
Step-by-step explanation:
1/2 acre 2 1/4 acre
------------ = -------------------------
3 days x days
using cross products
1/2 * x = 2 1/4 * 3
change 2 1/4 to an improper fraction (4*2+1)/4 =9/4
1/2 x = 9/4*3
1/2x = 27/4
multiply each side by 2
2 * 1/2 x = 27/4 * 2
x = 27/2
change back to a mixed number
x = 13 1/2
