It is A and D because as you can see it is using subtraction and multiplication and I’m sorry if I am wrong I can’t see much
Answer:
x=11
BC=19
Step-by-step explanation:
AB+AC=AC this is because B is in between A and C. So now we can substitute all of the line segments, so we have
x+2x-3=30 Now you add 2x and x
3x-3=30 Now you add 3 to both sides so you can get 3x alone on one side
3x=33 Now you divide both sides by 3 so you get the x alone on one side
x=11
The next step is to substitute x to find BC.
BC=2x-3 Substitute the x with 11
BC=2(11)-3 Then multiply 2 and 11 because that is the rule with parenthesis
BC=22-3 then subrtact the 3 from 22
BC=19
You can check your work by doing AB+BC=AC
11+19=30 substitute your answers and then add them together
30=30
