Find the perimeter of the figure.
gulaghasi [49]

Answer:

27in

Step-by-step explanation:

So, perimeter means we add all the sides together, as opposed to area, where we multiply them together.

9 - 5 = 4.

So the perimeter of the triangle would be:

3+4+\sqrt{3^2+4^2}=12

5 + 5 + 4 +1 (the 1 is from 4 -3) = 15

15 + 12 = 27

Are the graphs of the lines in the pair parallel? Explain.
jok3333 [9.3K]
So you gotta change the second one to slope int form and it will become -3y=18x-54 which means that it's A because parallel lines can't be parallel if the slopes are different. (pretty sure this is right but who knows)

Find the gradients for line A and B.<br><br> See pic attached
pogonyaev
Gradient is the difference between the y-axis and the x-axis
Gradient = y2-y1/x2-x1
Choose any two point making a triangle
Line B (0,8) (4,0)
This makes a triangle please go look at the graph once again! The the triangle should not have half squares but full!
Line A (5,14)(2,2)
Now plug in the variable
The difference between the Y and X
Line B 0-8/4-0
Line B gradient =-2
Line A 2-14/2-5
Line A gradient = +4

Finalized answer
Line B gradient = -2
Line A gradient = +4
