Answer:
She was driving for 5 hours
Step-by-step explanation:
Let us solve the question
∵ Kate begins with 16 gallons of gas in her car
∵ Her car burns 3 gallons of gas each hour
→ That means the rate of burn of the gas is 3 gallons per hour
∵ She ends her road trip with 1 gallon of gas left in the tank
→ That means she used the difference between 16 and 1 gallons
∴ The number of gallons she used = 16 - 1 = 15 gallons
→ By using the ratio method
→ Gallon : hour
→ 3 : 1
→ 15 : x
→ By using cross multiplication
∵ 3 × x = 15 × 1
∴ 3x = 15
→ Divide both sides by 3
∴ x = 5
∵ x represents the number of hours of her trip
∴ She was driving for 5 hours
It is 7 cuz u - 2 and add 5 and 2-6=4+5=9-2=7
9x^2+15x-14
=(3x-2)(3x+7) is your final answer. Hope it help!
