Answer:
Dimensions of photo excluding border:
x = 11 inches
y = 6 inches
Step-by-step explanation:
Let the length be 'x' and width be 'y'.
The width of a photo is 5 inches less than its length, that is:
x-5 = y
let 'X' be length of photo including border and 'Y' be the width of photo including border:
Where X = x+2 and Y = y+2
Now , we have X-5 = Y
and X*Y = 104 square inches
*putting Y = X-5*
X(X-5) = 104
⇒ X-13 = 0 or X+8 = 0
Hence X = 13 or X = -8
As length can not be negative, X = 13 inches
Y = X-5 = 13-5 = 8 inches
Dimensions of photo excluding border:
x = X - 2 = 13-2 = 11 inches
y = Y-2 = 8-2 = 6 inches

Step-by-step explanation:
I just multiplied everything, sorry if it's not correct.
Using proportions, it is found that the boat can go 6 m/s in still water.
<h3>What is a proportion?</h3>
A proportion is a fraction of a total amount, and the measures are related using a rule of three.
In this problem, we have that:
- Down the river, the speed is v + 2.
- Up the river, the speed is v - 2.
He goes twice as fast down the river, hence:
v + 2 = 2(v - 2).
v + 2 = 2v - 4
2v - v = 2 + 4
v = 6.
The boat can go 6 m/s in still water.

Using the vertex, it is found that the maximum height of the punt is of 27.7 feet.
The height of the punt, <u>after x seconds</u>, is given by:
It is a quadratic equation with coefficients .
The maximum value is the value of the function at the vertex, hence:
Applying the coefficients:
The maximum height of the punt is of 27.7 feet.
