An algebraic expression is looking something like this: 8x³ + 5
This expression has two terms; 8x³ and 5
The value of '8' in 8x³ is called COEFFICIENT
The value of '3' in 8x³ is called POWER or INDICES
The term 8x³ is called an exponent because it has power/indices
The letter 'x' in the term 8x³ is called VARIABLE
So, we want an expression with four terms
_____ ⁺/₋ _____ ⁺/₋ _____ ⁺/₋ _____
One term with an exponent ⇒ You can choose any letter and any power that will go with it, for example, 6x⁴
One term with a coefficient of 5 ⇒ 5x⁴
One term with three factors ⇒ This could be a combination of any three letters that represent three values for example 'abc'. This term means a × b × c, so it has three factors.
One constant ⇒ Choose any number, say 45
Make two of the terms like terms ⇒ We have 6x⁴ + 5x⁴; these two terms are alike, they are in term of x⁴
Putting the four terms together: 6x⁴ + 5x⁴ + abc + 45
Answer:
6m+7.5
Step-by-step explanation:
the arithmetic mean is the average of two numbers
it is given that a is average of 6m and 10
so 
b is the average of 4m and 4
so 
c is the average of 14m and 16
so 
now the average of a ,b and c is given by

We will use the proper formula and solve.
-> A diameter of 48 / 2 = 24 feet as our radius
Area:
A = πr²
A = (3.14)(24)²
A = 1,808.64 ft²
The circle has an area of about 1,808.64 ft²
Circumference:
C = 2πr
C = 2(3.14)(24)
C = 150.72 ft
The circle has a circumference of about 150.72 ft
