Nevermind I zoomed in. The answer is C because ≤ or ≥ needs a solid graph line, and since it is ≥ the shading should be on the top side of the line.
Answer:
16 and -4
Step-by-step explanation:
Let the 2 numbers be x and y with x > y
x+y=12
x-y=20
Adding the 2 equations, term by term on both sides, will eliminate y leaving an equation in x that we can solve
(x+x)+(-y+y)=(12+20)
2x=32
x=16
16+y=12
y=-4
16+-4=12
12=12
16--4=20
20=20
Trapezoid, height 7, bases 5 and 6, so
area = (1/2) (6 + 5)(7) = 77/2 = 38.5
Answer: 38.5
As a check it's a 7×5 rectangle plus a 7×1 right triangle, so
A = 7×5 + 7×1/2 = 35 + 3.5 = 38.5, good
