The answer for this is sally caught 16 trout because 8x2=16.
3.
a.∠BED = 90°
b.CD is perpendicular to AB. CD intersects AB at the midpoint
c. AE = 1/2AB
d. If AB=18, then AE is 9
e. CD is the midpoint of AB
4.If AB = 58, then


Answer:
-9x^2+13x+8
Step-by-step explanation:
Combine like terms-
(x^2 + 8x + 8) + (-10x^2 + 5x)
8x+5x = 13x
(x^2 + 8x + 8) + (-10x^2 + 5x)
-10x^2+x^2 = -9x^2
(x^2 + 8x + 8) + (-10x2 + 5x)
and 8 is just left over, so we put that all together and get...
-9x^2+13x+8
Good luck, have a great day!
