The area of a square is x2+14x+c.

let x = 4. find the area of the square
Area =

Find the length of the side of the square.
side =

Step-by-step explanation:

when x=4

area=4²+14×4+c=16+56+c=72+c

8²=64

9²=81

72+c=81

c=81-72=9

area=81  units²

length of each side=√81=9 units

7 weeks

step-by-step explanation:

convert each fraction to the least common multiple of 20, so 3/4 = 15/20 & 1/10 = 2/20, then divide 15 by 2 and you get a little over 7, so the food will last 7 weeks.
