Since each friend gets 2 apples.
So, n friends get apples= 2n
Thus equation becomes:
⇒
⇒
⇒
Thus there are 18 friends
Hence , Equation could you use to solve for the number of friends n:
Answer:
Step-by-step explanation:
Using FOIL (First, outer, inner, last)
First, we multiply 3x and x to get (First)
We then multiply 3x and 1 to get (outer)
Then 4 and x to get (Inner)
Then multiply 1 and 4 to get (last)
Since the quadratics are all positive, we add all the terms together to get:
. Since 3x and 4x are like terms, we add them together and simplify to get:
And since we can't simplify any further, that's our answer!
Hope this helps :D
