Answer:
Length - 70
Width - 30
Step-by-step explanation:
Let the width be x
Length is 40 more than width which makes length = x + 40
Perimeter = 2L + 2W
2(x + 40) + 2(x)
Open brackets
2x + 80 + 2x = 4x + 80
Perimeter = 200
200 = 4x + 80
4x = 200 - 80
4x = 120
x = 120/4
x = 30
Width = 30
Length = x + 40 = 70

Nope a trapezoid only has two right angles
Answer:
= 0.8 + -0.4y
Step-by-step explanation:
Simplifying
5x + 2y = 4
Solving
5x + 2y = 4
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '-2y' to each side of the equation.
5x + 2y + -2y = 4 + -2y
Combine like terms: 2y + -2y = 0
5x + 0 = 4 + -2y
5x = 4 + -2y
Divide each side by '5'.
x = 0.8 + -0.4y
