Answer:
6.09
Step-by-step explanation:
multiplayer ok so that is how I did it ok
So Length * Width = 480 in. sq.
L=1 1/5 or 1.2W
substitute the L for 1.2W
1.2W*W=480 in sq
divide both sides by 1.2
w*w= 400
W²=400
square root of both sides
Width = 20 inches
Length= (1.2width) or (20*1.2)
Length=24 inches
I hope this is right i think the answer is 40
believe what you're asking is to turn the trinomial into two binomials
So you first have to get 3x²; the only way to get this is
(3x )(x ) when multiplying that, you would get 3x²
when dealing with the -8x and the 4, you must find numbers that are factors of four (when multiplied together they will equal 4) and will multiply with the x's to get -8
(3x-2)(x-2)
you can tell that this is the answer because when you multiply though you will get:
3x-2x²-6x+4
or: 3x²-8x_4
Hope this helped
