I assume you mean A = k^2 + 19k + 60. If the values of k are natural numbers then the area must be A = (k + 15)(k + 4) which is the factored form of the quadratic. The only statement about the rectangle that can be made is that the long side of the rectangle is 11 more than the short side. Lets say that k = 10 then the dimensions of the rectangle are 25 and 14.

Rina8888 [55]

Answer:

Number of Fares to airport is 25 and number of fares from airport is 25.

Step-by-step explanation:

Given:

Total Number of fares =50

Let number of fares to airport be x.

Let number of fares from airport be y.

hence the equation can be framed as;

x+y=50 \ \ \ \ equation \ 1

Also Given

Total Money Collected = $375

Cost to airport = $10

Cost from Airport = $5

Total Money Collect is equal to Cost to airport multiplied by number of Fares to airport plus Cost from airport multiplied by number of Fare from airport.

10x+5y=375

Dividing by 5 on both side we get;

2x+y = 75 \ \ \ \ equation \ 2

Now Subtracting equation 1 from 2 we get;

(2x+y)-(x+y)=75-50\\2x+y-x-y=25\\x=25

Substituting the value of x in equation 1 we get;

x+y=50\\25+y=50\\y=50-25\\y=25

Hence Number of Fares to airport is 25 and number of fares from airport is 25.

What is the point slope equation of the line that has a slope of -5 and goes through the points (-4,9)
pshichka [43]
The equation for the point-slope form is y - y1= m(x-x1), where m is the slope. Using the coordinates and slope given, y - 9 = -5(x-(-4)), which simplifies to
y - 9 = -5(x + 4)
