Answer:
A is not a right triangle
B is a right triangle
Step-by-step explanation:
A.
6^2 = 36
12^2 = 144.
36 + 144 = 180
15^2 = 225
180 ≠ 225, so it is not a right triangle
----------------------------------------------------------------------------
B.
5^2 = 25
12^2 = 144
25 + 144 = 169
13^2 = 169
169 = 169, so it is a right triangle

Using the experimental probability of 7 pennies (a success) out of 20(number of trials) can give us an estimate of 7/20 or 0.035 or 35%
5x=2x=35
7x=35
x=35/7
x=5
5x=25 girls
2x=10 boys

That is called volume. there are 2 easy ways to find that. first way: multiply the length by the width by the hight. second way: using unit 1 cubes
Answer:
x = 45
Step-by-step explanation:
