By solving the linear equations we get the final values of x = 4 & y = 4.
What is the linear equation?
A linear equation is an algebraic equation of the form y=mx + b, where m is the slope and b is the y-intercept, and only a constant and a first-order term are included.
We have,
2x + 7y = -20 ----------(i)
x - 3y = 16 ----------(ii)
By multiplying equation (ii) with 2 we get,
2x + 7y = -20 ---------(III)
2x - 6y = 32 -----------(IV)
taking subtraction of equations (III) and (IV), we get
y = 4
by putting value of y in equation (ii) we get,
x = 4
Hence by solving the linear equations we get the values of x = 4 & y = 4.

Answer:
45
Step-by-step explanation:
F(x)=x+3 g(x)=x²-2
((5)²-2)+3(5)+4+3
25-2+15+7=45

Most of the information's required for finding the perimeter of the rectangle is already given in the question. Based on those details the answer to the question can be easily determined.
Length of the rectangle in question = 11 meters
Width of the rectangle in question = 4 meters
Then
Perimeter of a rectangle = 2 ( Length + Width)
= 2 (11 + 4) meters
= 2 * 15 meters
= 30 meters
So the perimeter of the rectangle in question is 30 meters as can be seen from the above deduction.
