Step-by-step explanation:
Formula: A = 2(wl+hl+hw)

Answer:
0.45hg
Step-by-step explanation:
Just move the decimal place two places to the left when converting something to hectograms, for example 1045 grams is 10.45 hectograms just move the decimal place twice to the left for this conversion.
Easy...
to even begin to factor..you must factor out a 3, to simplify your answer.
3(12

-7x-10)
Now, you can factor.

So..to find the answer...
12*-10=-120x
and
you would use -7x
What multiplies to -120..but adds to -7?
-15*8=-120
and
-15+8=-7
To find the answer, plug in what you know..
3(3x+2)(4x-5)
Thus, your answer.
