Factors of -100
-1,100 or 1,-100
-2,50 or 2,-50
-4,25 or 4,-25
-5,20 or 5,-20
-10,10
now through trial and error we add these together until we get 8 which is...
none of these, are you sure that you have the correct numbers?
y=x^2-2x-15 (1) y=8x-40 (2)
8x-40=x^2-2x-15
X^2+10x-25=0
(x-5)^2
×=5 y=0
A = (45/360)×16^2×pi
A = 32pi
Answer:
D=36
Step-by-step explanation:
All angles of the triangle add up to 180. Subtract 180-59-55=66
Then the missing measurement is a vertical which means that E=66.
So then 180-78-66=36
