Answer:
area = 22,272 
Step-by-step explanation:
area = length * width
to calculate the width, we need the first segment using the pythagorean theorem




length = 116 + 140 = 256
so
area = 87 * 256 = 22,272

Answer:
(-1.703, 2.396)
(1.37, 6.493)
Step-by-step explanation:
We can easily solve this question by using a plotting tool or any graphing calculator,
The solution to the system of equation is given by the intersection points between the graphs of
y1 = −x^2 + x + 7 
y2 = x^2 + 3x + 7
Please, see attached picture below.
The solutions are:
(-1.703, 2.396)
(1.37, 6.493)
