\left(a\left(a+b\right)-b\left(a+b\right)\right)

We take:
a\left(a+b\right)
And aply the law of the exponents:
=a^2+ab
we do the same process at the other side and we get:
=a^2+ab-ab-b^2
Now:
+ab-ab=0
So we get that:
=a^2-b^2

Find a:27=6:11, find a​
trasher [3.6K]

Answer:

a = 14.73

Step-by-step explanation:

This ratio can also be written like this:

\frac{a}{27} = \frac{6}{11}

Then you can cross multiply to get

11a = 6 x 27

11a = 162

Divide both sides by 11

11a / 11 = 162 / 11

a = 14.73
