Answer:
Let a be the width and b the length
a+3=b
a*b=54
a(a+3)=54
a^2+3a-54=0
a=6
Answer:

Step-by-step explanation:
Using:

we will have two solutions.
x^2-3x+1=0
So, a=1 b=-3 c=1

We have two solutions:

Ascending order...smallest to largest
-11 - 6x + 2x^2 + 8x^3 <==
Answer:
x>1.16
Step-by-step explanation:
Subtract 5 from each side to get 4x>14-8x
change the symbol from +8 to -8
4x> 14+ (-8x)
than add 8x to both sides
12x > 14
which would mean that x has to be greater than 1.16
x>1.16
