How do you find the length of the longest side of a rectangle with the perimeter of 90 length of 6x and 2x is the width?
33.75Let:Length = 6xWidth = 2xPerimeter = 2 * Length + 2 * Width90 = (2 * 6x) + (2 * 2x)90 = 12x + 4x90 = 16x16x = 90x/16 = 90/16x = 45/8x = 5.625Subst x = 5.625 to Length = 6xLength:= 6x= 6 * 5.625= 33.75thus, length of the longest side of a rectangle is 33.75.
What is 6x plus 5 equals 95-3x?
6x + 5 = 95 - 3x The main goal is to get "x" by itself. So you can first subtract 5 from both sides because whatever you do on one side of the equation, you do to the other side. 6x = 90 - 3x Next add 3x on both sides. 9x = 90 Last divide by 9 on both sides. x = 10
What is -6x plus 6x plus 7?
-6x^2 - 78x - 252 Improved answer: -6x+6x+7 When simplified = 7
Are 6x - 2 and 6x - 12 equal?
There is no possible value of 'x' for which (6x-2) can be equal to (6x-12).
10 times the quantity x minus 3 squared?
10(x - 3)2 = 10(x2 - 6x + 9) = 10x2 - 60x + 90 [ 10(x - 3) ]2 = 100(x2 - 6x + 9) = 100x2 - 600x + 900
