The length of a rectangle is twice its width. the perimeter is 60 ft. find its area.

200 feet squared

Step-by-step explanation:

W=Width

2W=Length

Perimeter = 2*Length + 2*Width

Now use substitution for the Length

60 = 2(2W) + 2(W)

60=4W + 2W = 6W divide both sides by 6

60/6 = 6W/6

10 = W

Width = 10 and Length is twice as long so it is 20. 10+10+20+20=60

The area is Length * Width = 20*10=200

the quotient is 4x^2 - 27x + 167 with a remainder of -996

step-by-step explanation:

in synthetic division, use -6 as the divisor and use the coefficients {4, -3, 5, 6}:

-6     )   4     -3     5     6

                -24   162 -1002

          4   -27   167   -996

thus, the quotient is 4x^2 - 27x + 167 with a remainder of -996.

note:   your "4x°-3x+5x+6" is ambiguous / incomplete.   i had to assume that you meant '4x^3 - 3x^2 + 5x + 6."
