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.
Answer:
50
Step-by-step explanation:
30% in decimal form is 0.3
0.3x = 15
divide both sides by 0.3
X = 50
