3πr3
Step-by-step explanation:
Answer: If the question is to solve for A: A= 
If the question is to solve for B: B= 15x+1-3xA+A
Step-by-step explanation:

Answer:
a) one solution, x=3
b) see below
Step-by-step explanation:
2x+3=4x-3
2x=6
x can only be=3
93
Straight lines are equal to 180, therefore 180-56 gives you 124 for the opposite angle to x. Adding 56, 124 and 87 gives you 267. 360-267=93
