Answer:
160 m²
Step-by-step explanation:
The surface area of the prism is the sum of the area of its surfaces. This prism has 5 surfaces, namely the front, back, right, left and bottom surface.
<u>Area of front surface</u>
Area of triangle= ½ ×base ×height
Base= 6 m
Height= 4 m
Area= 6(4)= 24 m²
<u>Area of back </u><u>surface</u>
Area of back surface
= area of front surface
= 24 m²
<u>Area of right </u><u>surface</u>
Area of rectangle= length ×breadth
Length= 7 m
Breadth= 5 m
Area= 7(5)= 35 m²
<u>Area of left </u><u>surface</u>
Area of left surface
= area of right surface
= 35 m²
<u>Area of bottom </u><u>surface</u> (base of prism)
Area of rectangle= length ×breadth
Length= 7 m
Breadth= 6 m
Area= 6(7)= 42 m²
The total surface area can be found by adding all of the surface areas we have found earlier.
Total surface area
= 24 +24 +35 +35 +42
= 160 m²
There are several ways to prove a mathematical statement. These ways include: by contradiction, by induction, contraposition, etc
<h3>How to prove the statement by contradiction</h3>
To prove the statement, we make use of proof by contradiction
From the question:
x is a composite number such that: x > 1
This means that 1 < a < x is a factor of x
This can be represented as:

Where:
- a and b are positive integers
- 1 < a, b < x
Assume that b is less than or equal to a.
Also, let
This means that:

The above becomes

Rewrite as:

So, we have:

The above means that:

The above inequality is a contradiction because, a number x cannot be greater than itself
This means that, the supposition is wrong.
Hence, the given statement has been proved by contradiction

To find the relationship between them, lets do some algebra:
f(x) = (7/10)^x
g(x) = (7/10)^-x
if we do:
f(x) * g(x) = 1
due to exponents multiplying addition law, therefore, the relationship, gives:
f(x) = 1 / g(x)
