Answer:
113.71 cm^2
Explanation m:
Area= a+b/2 h
18.2 + 9.2/2 •8.3 = 113.71
A = 2
b = -5
c = 6
The coefficients are 2 and -5
The constant is 6
If it bisect, then using the Line Bisector Theorem, it must be equal.
So x+6=4x-21
get like terms on 1 side
x+6=4x-21
-x. +21
27= 3x
x=9
plug the x in
CD= 9+6
CD=15
Answer:
22 pages per hour.
Step-by-step explanation:
5.5/15 = 0.36666
0.36666 * 60 = 22
