Answer:
Option D.
Step-by-step explanation:
The given expression is (5r + 2)(3r minus 4)
Convert this expression into an algebraic expression.
(5r + 2)(3r - 4)
By distribution law,
= 5r(3r - 4) + 2(3r - 4)
= 15r² - 20r + 6r - 8
= 15r² - 14r - 8
Now convert the algebraic expression into the language form.
15r squared minus 14r minus 8
Therefore, option D is the answer.

Answer:
The cost is $ 29.5.
Step-by-step explanation:
distance = 405 miles
Cost = $ 2.34 /gal
Average = 8.5 miles per litre
So, the amount of gasoline to travel for 405miles
= 405/8.5 = 47.65 liter
1 gal = 3.785 liters
So,
47.65 liter = 47.65 / 3.785 = 12.6 gal
So, the cots is
= $ 2.34 x 12.6 = $29.5
