Answer: 171 cm
Step-by-step explanation: im not sure if this is right but
9x12=108
9x7=63
108+63=171
Well lets see A, B and D are too large in the parenthesis that the numbers outside of the parenthesis will use to multiply considering 42 + 30.
6(7 + 5)
6(12)
72
The solutions for eq 1 can be solved with these 2 equations (5x + 6 = 41) and -(5x + 6 = 41)....so there are 2 solutions
the solutions for eq 2 can be found with these 2 equations (2x + 13 = 28) and -(2x + 13 = 28)...so there are 2 solutions
so both absolute value equations have 2 solutions
Answer:
the answer is A.
Step-by-step explanation:
Yes is A and the solution is that when you add negatives it restart number like 3x - - 3= 0
