We will start off by simplifying 4/8 to 1/2
then we will multiply the fractions because it says "of"
1/2 × 1/6=1/12
therefore the answer is C. 1/12
The answer for -2.5x-10=40 would be:
x = - 20.
The pattern is multiply by 4. so the next number is 4096
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
