4n^2 + 28n + 49 = 0 factorises to:
(2n+7)(2n+7) = 0
D=tr
r=d/t (I divided the t to the other side)
d=tr
t=d/r (I divided the r to the other side)
Based on the question, we know that the
original value multiplied by .855 will equate
to 432:
ticketstastyear * 0.855 = 132
Dividing each side by 0.855 results in the
amount of tickets sold last year:
ticketslastyear ~ 505.263
We round to the nearest whole number of
505.
The answer is 505
The expression that represents the perimeter of the rectangle is 4x² + 14x - 3 = 0
<h3>How to determine the expression</h3>
The formula for perimeter of a rectangle is given as;
Perimeter = 2 ( length + width)
Let the length of the rectangle be x
Width of the rectangle be y
From the information given, we have that;
y = 4 - 3/4x
Make into linear equation
y = 16x - 3 / 4x
Now, let's substitute the variables into the formula
Perimeter = 2 (
)
Find the LCM of the bracket
Perimeter = 
Perimeter = 
2x = 4x² + 16x - 3
Collect like terms
4x² + 16x - 2x - 3 = 0
4x² + 14x - 3 = 0
Thus, the expression that represents the perimeter of the rectangle is 4x² + 14x - 3 = 0
