Answer:
The given expression
at a = 2 , b = 5 and c = 4 is 37.
Step-by-step explanation:
Given : expression 
We have to evaluate the given expression
at a = 2 , b = 5 and c = 4
Consider the given expression
Substitute, a = 2 , b= 5 and c = 4
We have,

Simplify, we have,

We get,
= 37
So, The given expression
at a = 2 , b = 5 and c = 4 is 37.
Answer:

Answer:
Width of the room = 5 meters
Step-by-step explanation:
the rectangular living room is calculated as length * width
The area is given to be equal to 40 sq. meters (area = 40 sq. meters)
Let the width = x meters
Length = X+3 meters
Area = Length * Width
40 = X * (X+3)
40 = X^2 + 3X
We solve this quadratic equation
So x = 5 or x= -8
Width cannot be negative, so we reject x =-8
So x = 5 is the answer
