Answer:
46CM
Step-by-step explanation:
Perimeter = S + S + S + S + S + S + S +S
Perimeter = 9 + 7 + 8 + 5 + 5 + 8 + 2 + 2
Perimeter = 46 cm
The other 4 measurements:
5 is from the other side labelled 5 this is because they are equal.
8 is from the other side labelled 8 this is because they are equal too!
The twos are from the difference between 9 and 7.

<h2>
Step-by-step explanation:</h2>
If resistors are in series, so the current
is the same in all of them. In this problem we have four resistors. So, we can get a relationship between the Equivalent resistance of series combination and the four resistors as follows:

is the total resistance
. Moreover:

Therefore:

150.
You can read the uppermost point on the graph which is pretty much that point.
That would be a scalene because none of the sides are congruent (the same size)
Multiply both sides of the second equation by 4. That will give you -4x in the second equation which when added to 4x of the first equation will eliminate x.
Second equation:
-x + 3y = 6
Multiply the second equation by 4 on both sides:
-4x + 12y = 26
