I got you
Step-by-step explanation:
2 time 5 times 2 is 20. This minus 2 times 5 is 10 plus 3 is 13.
Answer:
1.8x-4
2.4x^2 -4x +1
3. No, while using it in perimeter it does get the same answer for both the beginning equation and final, area does not get the same answer in both.
Step-by-step explanation:
Its a square so all sides are equal.
1. Perimeter= 4 * side length
P=4(2x-1)
(4*2x)+(4*-1)
8x-4
2. Area=length x width
(2x-1)(2x-1)
You can use FOIL for this.
Firsts:2x*2x = 4x^2
Outsides:2x*-1 = -2x
Insides:-1*2x = -2x
Lasts:-1*-1 = 1
Now put them together with variables first.
4x^2 -2x -2x +1
Combine like terms
4x^2 -4x +1
Area= 4x^2 -4x +1
3. Replace x in perimeter.4(2x-1)
4(2(0.25)-1)
4(.5-1)
2-4
-2
Now in 8x-4.
8(.25)-4
2-4
-2
Both are equal so it works here
Area:(2x-1)(2x-1)
2(.25)-1
-.5*-.5
-1
Area final: 4x^2 -4x +1
4(.25)^2 -4(.25) +1
1^2-1+1
1-1+1
1
No its not equal so it does not work.
The answer is 11.5 meters. You have to multiply the height and width and then divide the volume by the product of the height and width's product.
