Answer:
(-6) - 7 and -6 - (-4)
Step-by-step explanation:
you have to find the rate of change.
this equals -13/4=3.25
There are 10 portions to the circle, and 7 of the 10 are shaded. 7/10 is 70%
6+7+8+9+10=40 ********************
If b is the base then the height h=b+6. As we have S=bh/2 then
36=b(b+6)/2;
b²+6b-72=0;
D/4=3²+72=81
b₁=-3-9=-12
b₂=-3+9=6.
The base is always positive so b=6, h=6+6=12.
Answer: base=6 ft, height=12 ft.
