Let's take a look at a perfect square trinomial.
We can distribute this expression to get
.
An important relation to recognize here is that the constant is the square of half of the x value.
Now, if we wanted to add a number to
to make a perfect square trinomial, we could have the value of x and then square it.
Half of 16 is 8, and 8 squared is
Answer:
Statement B is always correct
Answer:
39
Step-by-step explanation:
In order to solve this you have to fond r.
In 3r=18 you divide the 3 from both sides to isolate the variable.
18÷3=6 so you are left with r=6
So r is 6.
Plug that into 6r+3
6(6)+3
6×6=36
36+3=39
Answer:
x=17
Step-by-step explanation:
3x-15=20+16
