He simplified expression C because that is the only one that has only multiplications.
Standard form: y = x^2 + 10x + 21
Axis of symmetry: x = -5
X intercepts: (-3,0) (-7,0)
Y intercepts: (0,21)
Vertex: (-5,-4)
Answer:
It is B
Step-by-step explanation:
If you multiply 35 with the number on the left of the chart, it gives the exact number, thus it is correct
your answer is 39.
First you would add 7 and 2 to get 9. From there you would get the equation 3x/9=13.
Then you would multiple by the reciprocal, or 9/1 to cancel out 3x/9.
Then u multiply 9×13 because what u do to one side you have to do to the other.
Your equation should now say 3x=117.
Finally divide by 3 to solve for x.
X=39.
