Answer :
Given expression is
To make perfect square trinominal we use completing the square method
In completing the square method we add and subtract the half of square of coefficient of middle term
Here coefficient of middle term is -7
Half of -7 is
Square of is
=
So the expression becomes that gives perfect square trinomial
Hence , the value of 'c' is
The value for c will make the expression a perfect square trinomial is 49/4
How to determine the value of c?
The equation is given as:
x^2 - 7x + c
Take the coefficient of x
k = -7
Divide it by 2
k/2 = -7/2
Square both sides
(k/2)^2 = (-7/2)^2
The above represents the value of c.
So, we have:
c = (-7/2)^2
Evaluate
c = 49/4
Hence, the value for c will make the expression a perfect square trinomial is 49/4

Answer:
x= -1
Step-by-step explanation:
open brackets and calculate
3x - 12 + 6 = 5x -5 + 1
Calculate
3x - 6 = 5x - 4
transpose
3x - 5x = - 4 + 6
Calculate
- 2x = 2
x= 2/-2
x= -1
Answer:
X = -1
Step-by-step explanation:
3(x - 4) + 6 = 5(x - 1) + 1 -distribute
3x - 12 + 6 = 5x - 5 + 1 -combine like terms
3x - 6 = 5x - 4 -subtract 3x
-6 = 2x - 4 -add 4
-2 = 2x -divide by 2
-1 = x

Answer:
Volume of the cylinder (V) is given by:
where
r is the radius of the cylinder
h is the height of the cylinder.
As per the statement:
34 m on top and 27 m down on the right.
⇒Diameter(d) = 34 m and Height(h) = 27 m
We know:
Diameter = 2(radius)
⇒
Divide both sides by 2 we have;
m
Substitute these given values in [1] we have;
⇒
Simplify:
V = 24,501.42 cubic m.
Therefore, volume of the cylinder is, 24,501.42 cubic m.
The required volume of the cylinder is 24501.4 cubic meters
Use the concept of the cylinder defined as:
In mathematics, a cylinder is a three-dimensional solid that maintains, at a given distance, two parallel bases connected by a curving surface.
These bases often have a circular form (like a circle), and a line segment known as the axis connects the centers of the two bases.
Given that,
Height of cylinder 'h' = 27m
Diameter = 34 m
Since radius = diameter/2
Therefore, Radius 'r' = 17 m
We know that,
The volume of a cylinder,
V = πr²h
Put the values in this formula we get,
V = 17²(27)π
V = 24501.42 m³ [since π = 3.14]
Hence,
The volume of the cylinder is 24501.4 cubic meters.
