Answer:
x = 14
Step-by-step explanation:
If the perimeter is 80, then that is (x+6) + (x+6) + (x+6) + (x+6). If you want to find x, you have to get rid of 6. 6+6+6+6 = 24. The perimeter, 80, minus 56. You then divide 56 by 4 to get x. That is 14. To check, you find (14+6)*4. That is 80.
Answer:
x=6, y = -9
Step-by-step explanation:
6x + 2y = 18
-4x - 2y = -6
Add the two equations together to eliminate y
6x + 2y = 18
-4x - 2y = -6
------------------------
2x +0y = 12
Divide by 2
2x/2 = 12/2
x = 6
Then find y
6x+2y = 18
6*6 +2y = 18
36+2y = 18
Subtract 36 from each side
36+2y-36 = 18-6
2y = -18
Divide by 2
2y/2 = -18/2
y = -9
In a topographical map of a city, the vertices of the city limits are A(10,9),B(18,9),C(18,2),D(14,4.5),E(10,4.5). The coordinat

Answer:
41 square miles
Step-by-step explanation:
There are several ways you can compute the area of this polygon. We have elected to divide it into a rectangle and a triangle.
The rectangle has dimensions 8 × 4.5, so area ...
A = LW = 8 × 4.5 = 36 . . . . . square miles
The triangle has height 2.5 and base 4, so area ...
A = (1/2)bh = (1/2)(4)(2.5) = 5 . . . . . square miles
Then the total area is the sum of these:
36 + 5 = 41 . . . . . square miles
It either 20 or 25 percent. 25 is the 300 increase of 1200
