Answer:
D
Step-by-step explanation:
(8x15)/2, 60
60x10, 600
11.5 cm
33/2 = 16.5
16.5 - 5 = 11.5
Double Check
11.5 + 21.5 = 33
Answer:
a = 14.73
Step-by-step explanation:
This ratio can also be written like this:

Then you can cross multiply to get
11a = 6 x 27
11a = 162
Divide both sides by 11
11a / 11 = 162 / 11
a = 14.73
Answer:
y=2x-11
Step-by-step explanation:
It appears as if 12cm is half the length of the side so we can assume that the total length of one side is 24cm.
The area of a square is given by the equation
where s is the length of the side.

A=576
The area of this square is 576cm2.
Hope this helps!
