Answer:

Step-by-step explanation:

let width=x

length=x+3

x(x+3)=54

x²+3x-54=0

x²+9x-6x-54=0

x(x+9)-6(x+9)=0

(x+9)(x-6)=0

x=-9,6

x=-9 (rejected)

as width can't be negative.

hence width=6 units

What are the steps to 68 times 49
Anastaziya [24]

so basically what you would have to do is set up your numbers. it would look something like this. 68

                                    × 49

                                 -------------

and would then multiply 9 by 8, 9 by 6. put it down below the line while making sure to carry the numbers if need be. then do the same with the 4 times 8, and 4 by 6.
