He stops after driving 2 hours and fills the tank to capacity with 14.4 gallons. When Daniel arrives at his friend's house, he has 3.7 gallons of gas left. How much gas, in gallons, did Daniel use on the trip? *

just take the area of the square and then the area of the circle then subtract the circle area from the squares area

step-by-step explanation:

answer: 204

step-by-step explanation:

we are told that the revenue is

x⋅(4080−10x)=−10x^2+4080x

this is a quadratic function, so to maximize it we should find the x-value of its vertex. recall that the x-value of the vertex of the parabola ax^2+bx+c is given by the formula −b/2a.

so in this case, we have a=−10 and b=4080, so the x-value of the vertex is

−b/2a= −(4080)/2(−10)=204

the correct answers i think are b. and d.

give me brainliest if it is correct!

the answer is b.
