We know that area of the square is 141 square feet. Therefore, we can figure out the dimension of square using formula for area as shown below:

We know that fencing is used along the sides of the square. Therefore, amount of fencing required will be equal to perimeter of square.
Hence, we can write:


Upon rounding to nearest foot, we get the amount of fencing required as 48 feet.
Answer:
Jamal :
have = $18
need = $46-$18
= $28
saves = $5 each week
= $5 × 5 weeks
= $25 ( not enough )
Samuel :
have = $10
need = $46 - $10
= $36
saves = $7 each week
= $7 × 5 weeks
= $35 ( not enough )
thus, both boys would not have enough money to pay for the trip .
9x - 2 = 67
67 + 2 = 69
69 × 9 = 621
621 = x
I see you do K12 huh? XD Okay so, the answer should be below or above or something. lol Hope this helped!
-Twix
If x + 4y = 6 and you subst. -x+3 for y, you get x + 4(-x+3) = 6.
Then x - 4x + 12 = 6, or -3x = -6, or x = 2. Since y = -x+3, here y = -(2)+3 = 1.
Thus, the solution to this system of linear equations is (2,1).
