Answer:
Step-by-step explanation:
Putting value of y = 5
4(5)2 - 7(5) - 6
4(25) - 35 - 6
100 - 41

<h3><u>The function used to find the perimeter of a square, represented by y, given the length of a side, represented by x is: y = 4x</u></h3>
<em><u>Solution:</u></em>
Let "y" be the perimeter of square
Let the length of side be "x"
From given,
The perimeter of a square is the product of four and the length of a side
Which means,

Substituting the given variables,

Thus perimeter of square is y = 4x
80% bc 20/25 equals 4/5 and 4/5 equals x/100 and when you do that math it equals 80%
