Answer:
229/9 or 25.444 or 25 4/9
Step-by-step explanation:
brainliest is always appreciated :)
Because of rules of geometry we know that a+b=180 degrees so we can add the equations together and set that equal to 180 and solve
6x-48+4x+38=180
subtract 38 from both sides and add 48 to both sides
then add like terms
10x=170
and divide by 10 to get
x=17
Since you have to distribute both numbers, you'll end up with x^2-3x+4x-12 then simplify and it is x^2+x-12
The answer is D. 50 because x equals 7 so if you fill that in for 4x-3 and multiply it by 2, you get 50
