Step-by-step explanation:

V=(1/3)hpir^2
v=130
h=13
r=x
130=(1/3)(13)pix^2
times both sides by 3
390=13pix^2
divide both sides by 13
30=pix^2
divide both sides by pi
30/pi=x^2
sqrt both sides
x≈3.09
radius is abou 3 units
Do repeated addition to 1 and 1/2 to get the answer
5x² + 5x + 2x + 2
5x(x + 1) + 2(x + 1)
(5x + 2)(x + 1)
Answer:
6 - yup 7 - nope
Step-by-step explanation:
If the triangle satisfies the pythagoreon theorem, then it is a right triangle
so 6 is a yeah
then for 7, the hypotunese always is greater than the legs in a right triangle, so 7 is no
