Answer:
X=-1
Y=1
Step-by-step explanation:
6x-12y
-18
) 6x + 4y
-
-2
Subtract the two equations
6x - 12y - (6x + 4y) = -18 - (-2)
Determine the sign
6x- 12y - 6x- 4y
=-18 + 2
Simplify
-12y
- Ay
=-18 + 2
Solve the equation
Substitute
6×+4
-2
Solve the equation
X=
10 and (-9)
ex. 10+-9=1
ex. 10(-9)= -90
The rule for the area of a polygon is as follows:
Area of a Polygon = Apothem x Perimeter ÷ 2
So, add all the of the outside measurements together to find the Perimeter but I don't know where the Apothem in the polygons are.
I hope this gives you some sort of a lead. :)
7/8 .. *2 = 15/16
7/8 ...* 5 = 35/40
7/8 ...* 10 = 70/80
You can multiply the numerator and denominator by any number ( must be the same number), to result in an equivalent expression
