Step-by-step explanation:
So first cause of pemdas you do multiplication first so your left with 12 + 15 + 18 -4 then do add so then you have 45 - 4 and then you subtract so YOUR ANSWER IS 41
X=10
-8-x=-3(2x-4)+3x
-8-x=-6x+12+3x
-8-x=-3x+12
-x+3x=12+8
2x=20
x=10
You can check your solution by inputting 10 in all the x’s and solving it:)
I think the answer is d. The slope of AC=Slope of DF.
Hope this helped☺☺
