Let's me simply step-by-step.
Distribute the Negative sign:
x-5-(4x+2)
x-5-1(4x+2)
x-5-4x-2
(x-4x)+(-5-2)
-3x-7
the answer was -3x-7
and I hope that works you
The vertex is (12,-9). Hope this helps.
She will then have 3 rings
The side-splitter theorem is basically bisecting a side of a shape.
0= -3x+9
-9=-3x
3=x
Final answer: x=3
There is only one zero because it is linear, and can therefore only cross the x axis once.
