Answer:
x = -2,-4
Step-by-step explanation:
if you check it it will be 0 on both so its not both its just one but you can chose
Answer:
40
Step-by-step explanation:
The sum equals 80 80/2=40
DEF = BAC : x = 15 <==
once u allign ur triangles, u will see that there is a scale factor of 1.5.
6 * 1.5 = 9
1.5(x - 5) = 15
1.5x - 7.5 = 15
1.5x = 15 + 7.5
1.5x = 22.5
x = 22.5/1.5
x = 15 <==
For the volume you would use 1/2 b.h.h For a triangular prism. For an octagonal, you would use 1/2.a.p.h
b=Base
h=Height
(the other H) Hypotenuse
a=Apothom
p=Perimemter
