i do not know number 2 sorry

hope it helps have a great day :D
Answer:
Step-by-step explanation:
hello :
g(x) = (x+2)(x-4)/(x+2)(x-1)
1 ) this function no exist for if : x= -2 and 1
so the denominater is : (x+2)(x-1)
so : b= 2 and c=1
2) the x- intercept is : 4
so the numerater is : (x+2)(x-4)
g(x) =0 if : (x+2)(x-4)=0
means x-4=0 ... ( x+2 ≠ 0)
note :
g(x) ≠ (x-4)/(x-1) except in the case x ≠ -2
A)
It looks like the [irregular] hexagon has 3 rectangles and 2 triangles within it.
So let's exclude the triangular corners on bottom left and top right for now.
First we have a large rectangle covering most of the upper left of the polygon. 20 ft × 7 ft = 140 sq.ft.
Now we have a rectangle on the bottom right. The width is 11 ft, so take the 7 away from that, 4 ft. × 14 ft. on bottom. 4 ft × 14 ft = 56 sq.ft.
The last small rectangle fits on the right between the 2 other rectangles. It is 24-20 on top/bottom × 7-6 right/left. 4 ft × 1 ft = 4 sq.ft.
Now for the triangles: bottom left is 11-7 × 24-14 = 4 ft × 10 ft. 1/2bh = 1/2×10×4 = 20 sq.ft.
Top right is 24-20 × 11-5 = 4 ft × 6 ft. 1/2bh = 1/2×4×6 = 12 sq.ft.
B)
Add them all together for the total area (A):
A = 140 + 56 + 4 + 20 + 12 = 140+60+32
= 232 sq.ft.
Hope that explains it well enough! ;)
-15+2 means you add 2 to the negative number 15 so -15+2 will give us -13 which is the answer.
