Answer:

Step-by-step explanation:
We are to determine which of these expressions are equivalent to: 




Therefore, the two equivalent expressions are:

65 is the answer. Solve the first equation and then plug in.
A and b are perpendicular meaning that they intersect forming 90
b and c are parallel meaning that the intersection of c and a is also perpendicular
11x - 9 = 90 degrees
solve
11x - 9 = 90
add 9 to both sides
11x = 99
divide both sides by 11
x = 9
Hope this helps
Plug in -3 in the x.
4(2)(-3)= -24.
Answer:
b = -18
Step-by-step explanation:
-1/6b=3
Multiply each side by -6
-6*-1/6b=3(-6)
b = -18
