Answer:
Step-by-step explanation:
Jonah sister is 10 years old. Jonah is 8 years younger than twice hos sister age
j = 2s - 8
this is the equation.
You can solve it by substituting in 10 for s, because sister is 10 years old.
34;34;112
It's a Isosceles triangle so the equation is
x+17=4x-34
x-4x=-35-17
-3x=-51
x=-51/-3
x=17
17+17=34
4.17-34=34
6.17+10=112
I think the volume is 15
2.5 x 3 then multiply that by 2
