Answer:
$127.50
Step-by-step explanation:
To answer this you will need to figure out how many days each person is working each week based on their number of hours and how many hours they work. Use this to determine the number of dogs groomed and then multiply by the hourly rate.
Dana works 4 days (40/10) and Monique works 5 days (40/8).
Dana: 15 dogs per day x 4 days a week x $12.75 per dog = $765 a week.
Monique: 10 dogs per day x 5 days a week x $12.75 per dog = $637.50 a week.
765 - 637.50 = $127.50.
The difference is $127.50.
Answer:
D. 49p² - 64
Step-by-step explanation:
(7p - 8)(7p + 8)
Solving this requires the 'difference of squares' concept which states;
If (a - b)(a + b)
Then the solution must be a² - b²
Considering (7p - 8)(7p + 8) then the answer is;
(7p)² - 8² = 49p² - 64

Simplify the exponents and then multiply
Answer:
Step-by-step explanation:
The least number of degree is 3 and the third root should be (4 - i) to make polynomial rational.
<u>The polynomial is:</u>
- (x - 3)(x - (4 + i))(x - (4 + i)) =
- (x - 3)(x² -x(4 + i + 4 - i) + (4 + i)(4 - i)) =
- (x - 3)(x² - 8x + 16 - (-1)) =
- (x - 3)(x² - 8x + 17) =
- x³ - 8x² + 17x - 3x² + 24x - 51 =
- x³ - 11x² + 41x - 51
