Does 5cm 5cm 5cm make a triangle?
5cm, 5cm, and 5cm could represent the lengths of the sides of an equilateral triangle, or might indicate the length, width, and height of a cube.
What is the answer to this math problem The area of a rectangular computer screen is 4x2 plus 20x plus 16 The width of the screen is 2x plus 8 What is the length of the screen?
Area = 4x2 + 20x + 16 Width = 2x + 8 Length = ? To begin, we will factorise all the expressions Area = 4(x2 + 5x + 4) = 4(x+1)(x+4) Width = 2(x+4) Length = ? The formula for Area is given by: Area = Length . Width (A dot has been used to represent multiplication in the above formula so as not to confuse it with the variable x) Substituting in our expressions for Area and Width gives: 4(x+1)(x+4) = Length . 2(x+4) Dividing both sides by 2(x+4) to solve for Length gives an answer of: Length = 2(x+1) If you look at the width and the length expressions, the width is longer than the length (which shouldn't be possible). It is most likely a mistake in the question.
The perimeter of a rectangular playing field is 244 feet If its length is 2 feet longer than twice its width what are the dimensions of the field?
The answer is W=40 and L=82 If you're wondering how to solve it, then let "P" represent perimeter "L" represent length and "W" represent width. P=2L+2W L=2W+2 244=2(2W+2)+2W 244=4W+4+2W 244=6W+4 6W=244 244/6W= W=40 Now plug the 40 in for w in: L=2W+2 L=2(40)+2 L=80+2 L=82 final answer: L=82 and W=40
The area of a square is 230cm calculate the lower bound for the perimeter of the square?
Area = Length * Length Area = Length2 Length = Area Length = 230 Length = 15.16575..... -Oliver Crow
What are ways to represent linear equations?
One of the most common ways to represent linear equations is to use constants. You can also represent linear equations by drawing a graph.
