<h2>
The volume of a cylinder (y) = 
</h2>
Step-by-step explanation:
Given by question,
The volume of a cylinder = y, The radius of a cylinder(r) = x - 3 and
The height of a cylinder(h) = 2x + 7
To find, the volume of a cylinder (y) = ?
We know that,
The volume of a cylinder = 
⇒ 
⇒ y = 
⇒ y = 
∴ The volume of a cylinder (y) = 
Thus, the volume of a cylinder (y) =

Step-by-step explanation:
a = -2
b = 3
c = 5
<h2>Question:</h2>

= Solution,
= 3 ( - 2 ) × 5 - ( - 2 ) + 2 × 3
here ... ( + ) × ( - ) = ( - )
= - 6 × 5 - ( - 2 ) + 2 × 3
here .... ( - ) × ( - ) = ( + )
= - 6 × 5 + 2 + 2 × 3
= - 30 + 2 + 6
= - 30 + 8
here the ( - ) have greater variable so...
= - 22
hence - 22 is the answer . ....
(m+2)⁴ = ((m+2)²)²
= (m² + 4+ 2m)²
= m⁴ + 8 + 4m² + 8m² + 16m + 4m³ .........( (a+b+c)² = a²+b²+c²+2ab+2bc+2ac)
= m⁴ + 8 + 12m² + 16m + 4m³
