Answer:
1 1/4 in of material is cut off each board.
Step-by-step explanation:
To answer this, subtract 7 ft 10 3/4 inches from 8 ft.
First, rewrite 8 ft as 7 ft 12 inches.
Then subtract:
7 ft 12 in
- 7 ft 10 3/4 in
----------------------
1 1/4 in
1 1/4 in of material is cut off each board.
Answer:

<h3>Area, A(x) = 30x - x² , as a function of the length (x).</h3>
Step-by-step explanation:
Creative Landscaping has 60 yard of fencing with which to enclose a rectangular garden.
If the garden is X yards long, express the Gardens area as a function of length
Let x be the length of garden
So perimeter of rectangle = 60 yard
Perimeter = 2 * ( Length + width)
60 = 2 * ( x + width)
Width = 60/2 - x
Width= 30 - x

<h3>Area, A(x) = 30x - x² , as a function of the length (x).</h3>
Let us assume the two numbers to be "x" and "y".
Then
xy = - 24
x = - (24/y)
And
x + y = 2
Putting the value of x from the first equation in the second equation, we get
x + y = 2
- (24/y) + y = 2
- 24 + y^2 = 2y
y^2 - 2y - 24 = 0
y^2 - 6y + 4y - 24 = 0
y(y - 6) + 4(y - 6) = 0
(y - 6) (y + 4) = 0
When
y - 6 = 0
y = 6
Then
x + y = 2
x + 6 = 2
x = 2 - 6
= -4
And when
y + 4 = 0
y = -4
Then
x + y = 2
x - 4 = 2
x = 2 + 4
= 6
So the two unknown numbers are -4 and 6.
X + 7 > 0 , x > -7
2x -5 > 0 , 2x > 5 , x > 2.5
since that if x is more than 2.5 ,it will be more than -7
so the correct answer is x > 2.5
