What are the dimensions of a computer monitor if the length is 3 inches more than its width if the length is increased by 1 inch while the width remains the same the area is increased by 10 square inc?
x = width length = x + 3 (3+x)(x) = area (4+x)(x) = area +10 let area = y 3x + x^2 = y 4x+x^2 = y +10 substitute 4x + x^2 = 3x+x^2 + 10 x =10 = width length = 13
How much carpet is needed to cover 2 areas that are 10 ft by 3.5 ft and 13 ft by 4 ft?
You need to find the area which is length x width. For the first area: 10 x 3.5 =35 square feet. For the second area: 13 x 4=52 square feet.
What is 13 minus 10 per cent?
13 - 10% = 13 x (1 - (10/100)) = 13 x 0.9 = 11.7
What is the area of a rectangle with a perimeter of 28cm?
You can't tell. The perimeter doesn't tell you the area. There are an infinite number of rectangles that all have the same perimeter but different areas. Here are a few that all have perimeters of 28 cm: 1 x 13 . . . . . Area = 13 2 x 12 . . . . . Area = 24 3 x 11 . . . . . Area = 33 4 x 10 . . . . . Area = 40 5 x 9 . . . . . Area = 45 6 x 8 . . . . . Area = 48 7 x 7 . . . . . Area = 49
What is the answer to -3 - x equals 10?
If: -3-x = 10 Then: x = -13
What is 9 over 13 divided by 10 over 13?
(9/13) / (10/13) =(9/13) x (13/10) =9/10
What is the answer to 3 - (3 - 10)?
If: -3-x = 10 Then: x = -13
What is x plus 3 plus 10?
x + 3 + 10 = x + 13
What is the result of 3 x 2 plus 5 x 2 minus 13 minus 10 divide 2?
The equation:3 x 2 + 5 x 2 - 13 - 10 / 2= (3 x 2) + (5 x 2) - 13 - (10 / 2)= 6 + 10 - 13 - 5= -2
How many sq. ft. are in a room that measures 13X10?
To calculate the area of a room, you multiply its length by its width. For a room that measures 13 feet by 10 feet, the area is 13 x 10 = 130 square feet. Therefore, the room has an area of 130 square feet.
A circular mirror is surrounded by a square metal frame the radius of the mirror is 5x the side length of the metal frame is 15x what is the area of the metal frame write your answer in factored form?
To find the area of the metal frame, we first calculate the area of the circle and the area of the square. The radius of the mirror is (5x), so the area of the circle is (\pi (5x)^2 = 25\pi x^2). The side length of the square is (15x), so the area of the square is ((15x)^2 = 225x^2). The area of the metal frame is the area of the square minus the area of the circle: [ 225x^2 - 25\pi x^2 = (225 - 25\pi)x^2. ] Thus, the area of the metal frame in factored form is ((225 - 25\pi)x^2).
