Answer:
989 ft.
Step-by-step explanation:
7*13=91
<u>91</u> is the first rectangles area.
13+6=19
19*17=323
<u>323</u> is the second rectangles area.
25*23=575
<u>575</u> is the third rectangles area.
575+323+91=989
I think there is only one point x = -1.
Are you sure it's not x^2 + 1 = 0, if you had this equation the two points will be -1 and 1.
Or the equation was something like: x+1 =y?
If the equation is x+1=y.
First point: (-1,0)
Second point: (0,1)
