How to solve such questions?
Such Questions can be easily solved just by some Algebraic manipulations and simplifications. We just try to make our expression in the form which question asks us. This is the best method to solve such questions as it will definitely lead us to correct answers. One such method is completing the square method.
Completing the square is a method that is used for converting a quadratic expression of the form 
to the vertex form
. The most common application of completing the square is in solving a quadratic equation. This can be done by rearranging the expression obtained after completing the square: 
, such that the left side is a perfect square trinomial
= 
=

=
On comparing with the given equation we get
p = - 
and q = 
∴ = 
= - 34

Answer:
n = -9
Step-by-step explanation:-
Answer:
x = - 6.8
Step-by-step explanation:
Solve for 3/4(x) − 1.72 = −6.82
3/4 (x) = -6.82 + 1.72
3/4 (x) = -5.10
x = 4 * -5.1 / 3
x = 4 * - 1.7
x = - 6.8
This is just cylinder surface area, right? Equation for that would be 2πrh+2πr^2. If we input the data given from the image, it’d be (2 x π x 3.5 x 4)+(2 x π x 3.5 x 3.5). (4 is the height, and I found the radius by dividing the diameter, 7, in half, which is 3.5.) if u plug that into a calculator, u get 164.93.
