Answer:
I am guessing 145 so B
Step-by-step explanation:
Let's make W = width, and L = length.
What do we know? We know that P = 40 yards, and L = W + 1.5 .
The formulas for perimeter and area are:
P = 2W+2L
A = W*L
We can set P to 40, and since L = W+1.5, we can substitute that in for L.
40 = 2W + 2 (W+1.5)
40 = 2W + 2W + 3
37 = 4W
W = 37/4
We can plug that into L to find the length.
L = W + 1.5
L = 37/4 + 3/2
L = 43/4
Now, we plug into the area formula!
A = L*W
A = 43/4 * 37/4
A = 1591/16 or 99.43 yd^2
To solve this problem, let's try to find a point on the line. It appears that (6, 8) is a coordinate on the line. We can substitute this x-value of 6 into the functions and question whether it equals the y-value of 8.
Equation 1:
The first option choice is not the equation of our line.
Equation 2:
The second choice is the equation of our line. For more verification, we will check the other equations as well.
Equation 3:
The third choice is not the equation of our line.
Equation 4:
The fourth option is not the equation of our line.
The second choice is the equation of the line.
