How many side does the parallelogram has
Answer:

Step-by-step explanation:
we require 2 equations with the repeating digits placed after the decimal point.
let x = 0.888.. (1) ← multiply both sides by 10
10x = 8.888.. (2)
subtract (1) from (2) thus eliminating the repeating digits
9x = 8 ( divide both sides by 9 )
x = 
1.5(x+4)-3=4.5(x-2)
First, distribute 1.5 into x and 4, and 4.5 into x and -2, to get rid of the parentheses. Everything that we do to solve this equation is to isolate x to solve for its value.
1.5x+6-3=4.5x-9
Combine like terms on both sides (6-3).
1.5x+3=4.5x-9
Subtract 1.5x from both sides.
3=3x-9
Add 9 to both sides.
12=3x
Divide both sides by 3.
4=x
The answer is 4.

Answer:
please mark me brainliesf if it helps you
f(x) = -3x+1
or, y = -3x + 1
Interchanging the position of x and y, we get,
x = -3y +1
or, 3y = 1 - x
or, y = 1 - x /3
: . f^-1(x) = 1-x / 3
Answer:
Perhaps, she is interested in finding the area enclosed by this triangular park.
Step-by-step explanation:
The area of the triangle enclosed by the three points
A(1,1), B(1,4) and C(-3,4) in this question will be given by
|Ax ( By − Cy)+ Bx(Cy−Ay)+ Cx(Ay− By) |/2
=|1(4-4)+1(4-1)+-3(1-4)|/2=10/5= 5 sq. units.
