A or B. its a 50/50 here. I can't really tell whats on the graph.
Answer:
A. 8
Step-by-step explanation:
The angle shown is a 90 degree right angle (shown by the box where the vertex is)
We see that the first angle inside the right angle is 50 degrees, so the other angle must be 40 because the degrees must add up. We can set up an equation here.

After dividing both sides by 5, we get x = 8
Answer:
x: length
y: wide
x = 3y and x*y =192
=> 3y^2 = 192
=> y = 8 => x =3x8 = 24
=> Perimeter = (x+y)*2 = (8+24)*2 = 64
Answer:
D
Step-by-step explanation:
you can just find the value of y and try some number of x
i.e. if x = 0, both of them will be 0
x = 1
G(x) result is -2
F(x) result is 1
x= -1
G(x) result will be 2
F(x) result is -1
so from these we can prove that G(x) is bigger graph than F(x) but flip vertically by y axis
