Answer:
33
Step-by-step explanation:
If the equation

has undergo completing the square, the answer would be:


**In this example, since 6x is the middle term, what comes to my mind is the polynomial (x+3) because 2ab results into 6x. [from the special products lesson

]

So if the equation is equal to y, then this equation's

The vertex would be on the point (-3, -17)
Answer:
18
Step-by-step explanation:
33-15=18 I belive that is the mean
The sum of 15 and r.
Sum is the term used in verbal addition problems.
This is an expression therefore, you do not state what it equals. We no this because there is no equals sign.
Check the picture below.
bearing in mind that twin sides stemming from a common vertex, will make twin angles at the base, thus 74° has a twin.
