The length of a rectangle is 9 less than twice its width. it's area is 18 meters. find is dimensions pls help!!

6 x 3

Step-by-step explanation:

xy = 18

x = 2y - 9

systems of equations. solve the quadratic equation

2x^2 - 9x - 18 = 0

(x-6)(2x+3) = 0

Solution is x=6. So y = 2(6)-9.

{6,3}

.632

step-by-step explanation:

6 * 1/10 = 3/5

3*0.01 = 0.03

3/5 + 0.03 = .63

2*0.002 = .002

.63 + 0.002 = .632
