2nd one its like one big right angle so must add to 90
So (x+9)+2x=90
Because you an in partial products you add the numbers like regrouping your still adding in regrouping
Answer:
A
Step-by-step explanation:
Remember that the x-value of the vertex when an equation is given in standard form can be found with the equation
. So, we can take the coefficients from the equation and plug them in.

Now we know that the x-value of the vertex is 8. Next, the equation for the y-value is
, where h is the x-value of the vertex (8).

So the vertex is (8,-1).
Finally, the axis of symmetry is the x-value of the vertex, also called h.
Final answer, vertex: (8,-1) and axis of symmetry: x=8
Hope this helps!
5/6 and 1/6 are exponents to X. The X’s are divided by each other. does that make sense?
