Answer:
25
Step-by-step explanation:
12+13=25 so 25x5=125 and 125 divide 5=25
Change 4/5 - 2/3 so that the denominator is th same. Let’s try 15.
So, 12/15 - 10/15.
Then, subtract to get 2/15.

Since these are parabolas with y being squared, the standard form of such a parabola with vertex at (h, k) is
<span>x = a(y - k)^2 + h </span>
<span>There are no steps. Just look at what is inside the parentheses and compare it to (y - k) with k = -3. </span>
<span>Then look at what is added and compare it to h = -1. </span>
<span>For instance, A has (y + 1) in parentheses. So k = -1. And it has -3 added, so h = -3. That would be a vertex at (-3, -1).</span>
Answer:
x^2 + 3x - 18
Step-by-step explanation:
In order to solve this problem, I recommend using the FOIL method.
F = Front
O = Outer
I = Inner
L = Last
Start by multiplying the fronts which is x with x, which will give you x^2 (X to the second power).
Then, multiply x and -3, which gives you -3x. (Outer)
Third, multiply 6 and x, which gives you 6x. (Inner)
Finally, multiply 6 and -3, which gives you -18. (Last)
Now, there are like terms in the products that we just did which is 6x and -3x combine them together and you will get 3x.
So your results should be
x^2 + 3x - 18
Hope this helps!
