The area of square is : 25.0

The area of square is : 25.0

The idea is to multiply the side length by itself (since both length and width are the same in the case of a square). In other words, just multiply 5x times 5x.

If we are talking about a rectangle:Divide the area by the length of one side to get the length of the other side: Divide (x2 + 5x) by x and get (x + 5)Answer:x + 5

4 * 5x = 20x

It is 9x * 5x square units = 45x2 square units.

The area is 10x .

Each side of the square is 2x+1.5 and its area is (2x+1.5) squared

Area = length x width: so plug in the values you know.x2 +5x = (length) x (x) :now divide both sides by xx + 5 = length

1 Let length and width be 7x and 5x 2 So 7x*5x = 5040 or 35x2 = 5040 3 Divide each side by 35 and then square root both sides 4 Therefore x = 12 5 Length = 7*12 = 84 inches 6 Width = 5*12 = 60 inches 7 Check: 84*60 = 5040 square inches

Area=length x width=15625 Let width be x and length be 5x since length is 5x the width 5x times x = 5xsquared 5xsquared=15625 xsquared=3125 x=55.902=width 5x=279.51=length Perimeter equals the distance around the entire rectangle or 2 times the length + 2 times the width 111.804 (2w) + 559.02(2l)=670.824

5x + 20

5x ≥ 60x ≥ 12

Let the length be 5x and the width be x: 5x*x = 80 5x2 = 80 x2 = 16 x = 4 The width 4 meters and the length is 20 meters.

The quadratic equation of the square is probably x2-5x+6.25 = 0 because its discriminant is equal to zero giving the equation equal roots of x = 5/2 and x = 5/2

The square root of anything to an even power is that thing to half the power. √(5x^13) = √(x^12 5x) = √(x^12) √(5x) = x^6 √(5x) But is that really any simpler?

5x + 4 = 6x - 2Add 2 to each side of the equation:5x + 6 = 6xSubtract 5x from each side:6 = x

Suppose the side of the triangle is x metres.Then side of square is x + 10 metresso that the perimeter of the square is 4*(x+10) metresPerimeter of the triangle is 3*x metresSo 4*(x+10) = 3*(3*x) metresie 4x + 40 = 9x or 40 = 5x ie x = 8 metres

(5x + 1)2 = 25x2 + 10x + 1

-5x + 7 = 27Add (5x - 27) to each side ==> -20 = 5xDivide each side by 5 ==> -4 = x

5x + 9 = 4Subtract 9 from each side:5x = -5Divide each side by 5:x = -1

Area = L*W Area = 14* (5x-3) Area = 60x-42
