Answer:
A polygon is a very big catagory. For example, a triangle has three sides, while a quadrilateral has four sides.
A triangle would be, A=h*w/2 (h being hight, and w being width)
A quadrilateral would be, A=h*w
Answer:
Last option (bottom right)
Step-by-step explanation:
Rotate figure H 180° about the origin, then the figure will turn upside down and will be at quadrant 4, then translating it to 2 units right, you'll get figure K

Answer:
x = -8
y = 7
Step-by-step explanation:
5x + 7y = 9
2x - 3y = -37
1.) First, multiply each side to match either y-values or x-values. (In this example, we'll use match x-values)
10x + 14y = 18 (multiplied by 2)
10x - 15y = -185 (multiplied by 5)
2.) Then, subtract the entirety of one equation to isolate the y-value.
10x + 14y = 18
-10x + 15y = 185
3.) Add and subtract values and divide to find y.
29y = 203
y = 7
4.) Plug-in y to solve for x into one equation, or repeat steps 1-3.
15x + 21y = 27
14x - 21y = -259
29x = -232
x = -8
Answer:
y=4x-5
Step-by-step explanation:
-3y = -12x+15. y = (-12x+15)/(-3). y = (-12x/-3)+(15/-3). y = 4x-5.
4*2=8. 8/2.5=3.2. The height is 3.2 meters.
