V = 16, E = 37, F = ?

F + V = E + 2

F + 16 = 37 + 2

F + 16 = 39

F = 39 - 16

F = 23

F + V - E = 2....solving for F
V = 16
E = 37
just a matter of subbing and solving
F + 16 - 37 = 2
F - 21 = 2
F = 2 + 21
F = 23

Please help! I’m very confused on this question. I’m not very good at geometry.

Well, to find the perimeter we have to add all of the side lengths, so let's do that:

2x+3 +2x+3 +2x

And we know that this equals 36 so let's solve for x

2x+3+2x+3+2x = 36

6x+6 = 36

6x = 30

x = 5

So we know know that x = 5.

Now all you have to do is plug in the values of x into the lengths

2(5) + 3

= 10+3

= 13 is the length of two of the sides.

= 2(5)

= 10

And 10 is the length of the last side.

15 points !!<br> Estimate the solution to the following system of equations by graphing.

Marina86 [1]

For this case we have the following system of equations:
-4x + 5y = 8
6x - y = 11
The solution is the ordered pair where both functions intersect.
In this case, the point of intersection is:
(x, y) = (5/2, 7/2)
Answer:
(x, y) = (5/2, 7/2)
