Answer:
7
Step-by-step explanation:
10x-2=9x+5 because the angles are the same as m and n are parallel.
10x=9x+7
x=7
Answer:Solve for h V=1/3pir^2h. V=13πr2h V = 1 3 π r 2 h. Since h h is on the right side of the equation, switch the sides so it is on the left side of the equation. 13⋅(πr2h)=V 1 3 ⋅ ( π r 2 h ) = V. Simplify the left side.

<em>First evaluate the operations inside of the brackets</em>
-8 + 2[5 + (-4 + 1)2] <em>evaluate (-4 +1) because it is surrounded by parenthesis</em>
-8 + 2[2 + (-3)2]) <em>multiply (-3)2
</em>-8 + 2[2 - 6] <em>subtract 2 - 6 because it is surrounded by the brackets (parenthesis)
</em>-8 + 2(-4) <em>multiply 2(-4)</em>
