Answer:
k+7
k-7
or k+7/k-7
Step-by-step explanation:
Given :
Total money Beto have , P = $12 .
Cost per gallon , c = $3.75 .
To Find :
Ordered pair of lading number of gas to the total cost of gas includes the greatest amount of gas she can buy .
Solution :
Now , number of gallons she can buy for $12 is :

So , the greatest amount of gas she can buy with $10 is 3.2 gallons .
Therefore , the ordered pair is ( 3.2 , 12 ) .
Hence , this is the required solution .
X^2 + 3x = 24
completing the square
(x + 1.5)^2 - 2.25 = 24
(x + 1.5)^2 = 26.25
x + 1.5 = +/- sqrt26.25 = +- 5.123
x = -1.5 + 5.123 = 3.62 to nearest hundredth and
x = -1.5 - 5.123 = -6.62 to nearest hundredth
solution set is {-6.62, 3.62}
Sum of -2x^-3x is -5x and sum of x^+7x is 8x hope this helps answer my question please !!
3=3*1
8=1,2,4,8
the greatest common factor is 1
