Answer:
A
Step-by-step explanation:
Given
(3x² - 11x - 4) - (2x² - x - 6)
Distribute both parenthesis, noting the second is distributed by - 1
= 3x² - 11x - 4 - 2x² + x + 6 ← collect like terms
= x² - 10x + 2 ← this is a quadratic with 3 terms, thus trinomial → A
Answer:
the tank can hold 12.5 gallons when it is full
Step-by-step explanation:
Let's assume
tank can hold 'x' gallons when it is full
we are given
The gas gauge in a car shows it has 40% of a tank of gas
So, gas in car is

and we have
the car has about 5 gallons
so, we can set it equal
and then we can solve for x



Multiply both sides 5



we get

So, the tank can hold 12.5 gallons when it is full
