Answer: gcf is 7
Step-by-step explanation:
Answer:
assuming that you start at the origin (0,0)
(-4,-1) would be the poiny
x coord = -4
y coord = -1
the point is in the 3 quadrant
Step-by-step explanation:
You have to move variables on one side and constants on the other
aby - b + b = c + b
aby = c + b
y = (c + b)/ab
12%
40% = 0.4
30 = 0.3
0.3 x 0.4 = 0.12
0.12 = 12%
1. BC is 1+3=4 (units)
2. AD is 3+5= 8 (units)
3. Draw the altitude CH from point C, as shown in the figure.
4. Then triangle CHD is a right triangle, with hypothenuse CD, and sides HD and CH.
5.



6. AB=CD=4.47 because the trapezoid is isosceles.
7. P= BC+AD+AB+CD=4+8+4.47+4.47=20.9 (units)
