The answer would be
3x² + 6
Answer:
B. 2
Step-by-step explanation:
Assuming the term is meant to look like this: -3x², then the answer is B.2. An exponent is a superscript (super means above, script means writing) that tells you to multiply something by itself.
In this case, -3x² means -3·x·x
If it was written as (-3x)², it would mean (-3x)·(-3x)
Independent variables must be the amount of cans you buy of cat food. The dependent variable, well that must be the cost. Depending on how many cans you buy, the cost changes! :)
You can use this ratio:
1hour/60minutes=0.73hours/Xminutes
and cross multiply
so x= 43.8 minutes
