Answer:
A. X+6=6x
X+6=6(x)
Step-by-step explanation:
B. 3+6=3×6
9=18
I think the correct answer is B. It is the triangle case SSA that may have one, two, or zero solutions. This case can have either number of solutions but it depends on the sides of the triangle given. Having one solution can be all of the cases except SSS, having 2 solutions can only be applied to SSA.
12 x .75 = 9 ft (horizontal)
4 x 1.5 = 6 ft (vertical)
Simply distribute the -3 across the b and -7.
-3(b - 7) = (-3 * b) + (-3 * -7) = -3b + 21
Hope this was helpful, if it wasn't just drop me a DM explaining what didn't make sense.
