Answer:
-4x² - 2xy + 5y²
Step-by-step explanation:
Step 1: Write expression
(3x² - 5xy + 2y²) - (7x² - 3xy - 3y²)
Step 2: Distribute negative
3x² - 5xy + 2y² - 7x² + 3xy + 3y²
Step 3: Combine like terms
-4x² - 2xy + 5y²
Step-by-step explanation:
p = 2r + pi×r
p = r(2 + pi)
r = p/(2 + pi)
Find the number of miles driven by subtracting the odometer readings:
74545 - 74233 = 312 miles driven.
Divide miles driven by gallons of gas used:
312 / 9 = 34.66 = 35 miles per gallon.
