Since the family spends ten minutes on average per shower and there is 2.5 gallons spent per minute, 25 gallons are used per shower and with 4 shows per day, 100 gallons are used per day, so in 30 days they use 3,000 gallons of water, since water costs $1.50 per 1000 gallons, showering only costs them $4.50 per month
First degree polynomials means that the maximum power x is raised up to that does not have a coefficient 0 is 1. And here we have a term ax^2 which means it could not be a first degree polynomial if a has a positive or negative value. Thus, letter a in this case should be 0 in order for this to be a first degree polynomial of x.
Answer:
You use the product of powers law of exponents to combine the exponents; this law says to add the exponents.

Answer:
10²
Step-by-step explanation:
Another way of phrasing "10 sets of 10 sit-ups" is "10 sit-ups, 10 times," or mathematically, 10 x 10. Another way of writing repeated multiplication is through <em>exponents</em>. Since we have 2 10's multiplied together, we can rewrite our expression as 10².
