Answer:
35
Explanation:
Recall that (a+b)^2=a^2+2ab+b^2.
We can rearrange it in a way that would make it easier to solve our problem:
(a^2+b^2)+2ab
Now, we just plug in 25 for a^2+b^2, and plug in 5 for ab:
25+2*5
=25+10

The yearly cost in dollars, y, for a member at a video game arcade based on total game tokens purchased, x, is y =y equals Start
const2013 [10]

Answer:

y = \frac{1}{5}x

Step-by-step explanation:

Given

Yearly Cost for members; y = \frac{1}{10}x + 6

Required

Determine the yearly cost for non members

From the question, we understand that:

<em>A non member pays $0.20 for each game;</em>

Yearly cost is then calculated as thus;

y = Amount * Number of Games

Where:

Amount = $0.2 and Number of Games = x

y = 0.20 * x

Convert 0.2 to fraction

y = \frac{2}{10} * x

Divide the numerator and the denominator by 2

y = \frac{1}{5} * x

y = \frac{1}{5}x

<em>Hence, the yearly cost for non members is </em>

y = \frac{1}{5}x
