Step-by-step explanation:
step 1. x + 4.75 - 6.55 = 5.43
step 2. looks like b is the only answer.
The plane from new york to london fly 515.2 km per hour compared to the plane from denver to hartford .
<h3>What is Ratio ?</h3>
Ratio is when a number is divided by any other number and written in the form p:q.
It is given in the question that
A commercial airplane broke a record when it traveled 5,540 kilometers from new york to london in 5 hours .
a different airplane traveled 2,964 kilometers from denver to hartford in 3 hours.
The airplane travelled 5,540 kilometers in 5 hours
In 1 hour , the commercial airplane covered 5540/5 = 1108 km.
In 1 hour , the other airplane covered 2964/5 = 592.8 km
Therefore the plane from new york to london fly 1108- 592.8 = 515.2 km per hour compared to the plane from denver to hartford .

I agree. Both of the equations come out to 2x^2+14x+20
(2x+10)(x+2)
Use the FOIL method
2x^2+4x+10x+20
Combine like terms
2x^2+14x+20
(2x+4)(x+5)
Use the FOIL method
2x^2+10x+4x+20
Combine like terms
2x^2+14x+20
-28 x^2 + 42 x^3 + 21 x^4 is your Answer
