Answer:
x = 19
Step-by-step explanation:
123°+3x = 180°
3x = 180°-123°
3x = 57
x = 57/3
x = 19
The reason why we use 123° + 3x = 180° because both are adjacent angles. Adjacent angles add up to 180°
D. (-2,-6) (1,3) is the correct answer I believe
States were able to choose if they wanted to be free states or not which cause some states up north to hV SLAVE WHICH CAUSED CONTROVERSY
1) You need to work this problem backwards.
x=0 and x=5 and those are the roots so the factoring must have looked something like this:
(x-0)(x-5) Then you would FOIL it:
x^2-5x-0-0 Then simplify:
x^2-5x.
2) Do the same thing with this problem.
x=7 and x=7
(x-7)(x-7)
x^2-7x-7x+49
x^2-14x+49
I hope that this helps.
