Answer: 9
Step-by-step explanation:
To find the perimeter of the Triangle, add all 3 sides together
So 2x + 3x + 4x = 81
9x = 81
Divide both sides by 9
x=9
Answer: 24 inches.
Step-by-step explanation:
You can find the perimeter of the polygon by adding the side lengths.
First, find the missing side lengths.
There is a short space between the right side of the square above the triangle. The triangle is 3 inches tall, and the square is 4 inches tall, so that space is 1 inch long.
We can then add the sides to find the perimeter:
4 + 9 + 5 + 1 + 5 = 24 inches long.
Keep in mind that the three inches of the triangle is not included in the sum because it is not on the outside of the polygon. The perimeter only includes the lengths of the exterior sides.
Answer: The answer is 64
Step-by-step explanation:
you have x squared so you do 10 minus its self and you subtract 18 giving you 8 then you replace the x squared and do 8 x 8 giving you 64
y=-3x+4 = x = 4/3
y=3x-2 = x =2/3
