Answer:
6 inches
Step-by-step explanation:
The formula for the area of a triangle is
b - base
h - height
the first step is to add the information that we know into the formula.
We know the area = and the height = 5 inches
if we had both the base and the height, the next step would be to multiply
b x h then half the answer to work out the area but as we already have the area () we need to work in reverse.
15 x 2 = 30
what is 5 multiplied by to get 30?
5 x ? = 30
30 ÷ 5 = 6
∴ the base = 6inches
to check if our answer is correct, we can place these numbers into the formula
A =
A = (30 ÷ 2 = 15)
A = 15
I hope this was helpful :-)
I think you're factoring this...? You can do that by grouping here. Put the 4 terms in groups of 2 and factor out the greatest common factor. What's left behind is a common binomial factor that can also then be factored out. Like this:
Factoring what we can out of both sets gives us this:
The 2n-5 is a common factor between both the sets of terms, which in turn can also be factored out:
I'm not exactly sure what you are doing with this, but we can keep factoring for the sake of completeness. The 5 n-squared term can also be factored:
and 
and 
so 
. Simplifying that down its simplest is this:
So your three factors for that polynomial are
