Answer:
-2
Step-by-step explanation:
as x goes up 1 y goes down 2
slope is change in y over change in x
-2/1=-2
8(7x-1)+4(x+5)
multiply; 8 x 7=
56x + -1 + 4x +5
reorder the terms;
-1 + 5 + 56x + 4x
Combine like terms; -1 + 5 = 4
4 + 56x + 4x
Combine like terms again; 56x + 4x = 60x
4 + 60x
Answer:
83.4
Step-by-step explanation:
Area of a Regular Polygon: L (of side) times apothem (height) x 1/2
L : 13.9
Looking at the triangle we can assume the height would be 12 since its logical that 3 of the 4 lines can fit in the middle of the triangle.
H: 12
13.9 x 12 = 166.8
166.8/2 = 83.4
Answer:
H= 10
Step-by-step explanation:
Hypotenuse formula if you have the other 2 sides.
