Answer:
6x + 14
Step-by-step explanation:
Area = side x side
Factor the quadratic:
2x^2 +10x / +1x +5
2x(x+5) 1 (x+5)
(2x + 1) (x+5)
^These are your two sides
Perimeter =2L + 2W
(2(2x+1)) + (2(x+5))
4x+4+2x+10 = final answer 6x + 14
By solving a system of equations, we will see that the width is 170ft and the length 275 ft.
<h3>
How to get the dimensions of the base?</h3>
For a rectangle of length x and width y, the perimeter is:
P = 2*(x + y).
Here we know that:
x = 2y - 65ft
p = 890ft = 2(x + y)
So we have a system of equations.
To solve this, we need to replace the first equation into the second one:
890ft = 2(x + y)
890ft = 2(( 2y - 65ft) + y)
Now we can solve this for y.
890ft = 4y - 130ft + 2y
890ft + 130ft = 6y
1020ft/6 = y = 170ft
So the width is 170ft, and we know that:
x = 2y - 65ft = 2*(170ft) - 65ft = 275ft
So the length is 275 ft.

Answer: The new length is: (y - x) metres.
Step-by-step explanation:
If we have a piece of string that is y metres long, and we cut x metres of strings from it, then the new length of the string will be equal to the difference between the initial length and the amount that we cut off.
So the initial length is y metres.
We cut x metres.
The new length is: (y - x) metres.
Substitution for both equations is (-3,1)
