Answer:
44 units
Step-by-step explanation:
We know that in a parallelogram opposite sides are equal.
Therefore AB=CD and AD=BC
Consider AB=CD,
⇒4y-2=2y+6
⇒2y=8
⇒y=4
Now consider AD=BC,
⇒3x-1=2x+2
⇒x=3
now substituting values of x and y in the expressions of sides,
we get AB=CD=14 units and AD=BC=8 units
Therefore perimeter of parallelogram is 2*(AB+BC)=2*(14+8)=<u>44 units</u>
Solution:
<u>Note that:</u>
- Given points = (-2,y) and (0,-4)
- Slope = -13/2
- Formula: y₂ - y₁/x₂ - x₁
<u>Forming an equation:</u>
- y₂ - y₁/x₂ - x₁ = Slope
- => -4 - y/0 - (-2) = -13/2
<u>Solving the equation:</u>
- => -4 - y/0 + 2 = -13/2
- => -4 - y/2 = -13/2
- => -4 - y = -13
- => -y = -13 + 4
- => -y = -9
- => y = 9
The missing value is 9.
Answer:
You will want to set up the ratio for each and set them equal to each other. Then you can cross multiply to verify if you get the same answer. Another strategy is to set up each ratio and then reduce to lowest terms to see if you get the same fraction.
