Answer:
B,C
Step-by-step explanation:
So all you have to do is use the pythagorean theorem to solve this (a²+b²=c²).
Plug in the two shorter sides for a and b and the long side for c. If both sides equal the same thing then it will make a right triangle.
A) 5²+6²=9²
25+36=81
61≠81
B) 0.25+1.44=1.69
C)49+576=625
D) 100+256≠361
E)1+4≠9
Answer:
80
Step-by-step explanation:
The equations would be:
x=18+3y
x+y=54
(substitute x in the second equation with 18+3y)
18+3y+y=54
(combine like terms and solve for y)
y=9
(plug y into the second equation to find x)
x+9=54
x=45
I think it is hexagon. It says which polygon at the bottom, and hexagons have six sides like the figure above.
