23/7+61/3 is done first due to PEMDAS
so the lcm of 7 and 3 is 21
So 23*3 + 61*7 divide the whole by 21 which is 7*3
The answer will come out to 496/21
Then outside the bracket the whole is times 34/3
So 34/3*496/21=
16864/64
We can’t simplify it more so that’s the answer
You only showed B but it’s not B
Answer: Lines R and B are perpendicular
Step-by-step explanation: Slope of R is -1 and the slope of B is 1. Perpendicular lines have opposite slopes
The correct answer is D...
