Answer:
72 degrees
Step-by-step explanation:
180-36=144
144/2=72
Answer:
A prism is a polyhedron with two parallel, congruent faces called bases that are polygons
3 x 0.79= $2.37
2 x 1.29= $2.58
4 x 0.15= $0.60
9 x 0.38= $3.42
$2.37 + $2.58 + $0.60 + $3.42= $8.97
$20.00 - $8.97= $11.03
The answer is $11.03
replace x^2 with m and try to solve
-3 m^2 +27 m +1200 =0
factor out -3
-3(m^2 -9m-400)=0
-3 (m-25) (m+16) =0
using the zero product property
m-25 =0 m+16=0
m=25 m=-16
then substitute m=x^2 back in
x^2 = 25 x^2 = -16
x take the square root of each side
x = +- sqrt (25) if you know complex number x = +- sqrt (-16)
x = +-5 x = +- 4i
Answer: +5, -5 , +4i, -4i
