Answer:
x = 13
Step-by-step explanation:
Now since the lines are parrarel, the intersection points are alternate to each other. Therefore, A = B.
Solve:
8x + 2 = 14x - 76
2 + 76 = 6x
78 = 6x
x = 13
Let x = the length of a side of the square (m).
The area is
A = x²
The perimeter is
P = 4x
The rate of change of P with respect to x is
P'(x) = 4 (independent of x)
When A = 49 m², then x = 7 m.
The rate of P is 4.
