What do you do to find the surface area of a shape?
Rectangular Prisim 2x(area of front)+2x(area of side)+x2(area of length) Cube 2x(area of side)+2x(area of side)+2x(area of side)
How does the perimeter and area of a square change when its dimensions change?
A 3 x 3 square has perimeter 12 and area 9 A 6 x 6 square has perimeter 24 and area 36 Double the dimensions, double the perimeter, quadruple the area. Mathematically, a square with side x has a perimeter of 4x and an area of x2 Doubled, a square with side 2x has a perimeter of 8x and an area of 4x2
What is the length of one side of this square 4x2 - 4xy plus y2?
4x2 - 4xy + y2 = (2x - y)2 so the length of the side of the square must be 2x-y.
What is a variable expression for the perimeter of the square with side 2x plus 1?
Perimeter of a square = 4 * sideP = 4 * (2x +1)P = 8x + 4
We are interested in the dimensions of a certain square. A rectangule has length twice the side of this square and width three less than theside If two areas are equal what are the square's dimension?
Area of square = x2Area of rectangle = 2x * (x-3)The two area are the same so x2 = 2x2 - 6xso x2 = 6xso x = 6The square has sides of length 6A+ = x2 = 2x2 - 6
What is the area of the square with a side length of 2x?
The area is 4x2 square units
What is the area of a square in terms of x if one side has 2x-7 units?
(2x-7)(2x-7) = area 4x2-28x+49 = area
What is the area of the square whose side measures 2x-5 cm?
It is: (2x-5)(2x-5) = 2.5 square cm when solved as a quadratic equation
What do you do to find the surface area of a shape?
Rectangular Prisim 2x(area of front)+2x(area of side)+x2(area of length) Cube 2x(area of side)+2x(area of side)+2x(area of side)
If the perimeter of a square is 8x plus 6 what is its area?
Each side of the square is 2x+1.5 and its area is (2x+1.5) squared
How do you find the area of a square when the length of a side is 2x-1?

How does the perimeter and area of a square change when its dimensions change?
A 3 x 3 square has perimeter 12 and area 9 A 6 x 6 square has perimeter 24 and area 36 Double the dimensions, double the perimeter, quadruple the area. Mathematically, a square with side x has a perimeter of 4x and an area of x2 Doubled, a square with side 2x has a perimeter of 8x and an area of 4x2
Why does the perimeter of a square double when you double the sides of a square?
The perimeter is the sum of the sides. So if a square has a side of length 1, its perimeter is 1+1+1=1 = 4 If a square has a side doubled to length 2, its perimeter is 2+2+2+2 = 8, or double what it was before. Mathematically, if each side is length x it perimeter is x + x + x = X = 4x If each side is length 2x, its perimeter is 2x +2x+2x+2x = 8x
What is the length of one side of this square 4x2 - 4xy plus y2?
4x2 - 4xy + y2 = (2x - y)2 so the length of the side of the square must be 2x-y.
What is a area of a sector formed by central angles 2x?
2x*r2 square units where r is the radius and 2x is the angle (measured in radians).
What is a variable expression for the perimeter of the square with side 2x plus 1?
Perimeter of a square = 4 * sideP = 4 * (2x +1)P = 8x + 4
