Answer:

1. 15xy + 9y

2. 4xy + 6y

3. 4xy + 8y

4. 21xy + 6y

Step-by-step explanation:

You just have to expand it:

3y(5x+3)

= 3y(5x) + 3y(3)

= 15xy + 9y

2y(2x+3)

= 2y(2x) + 2y(3)

= 4xy + 6y

4y(x+2)

= 4y(x) + 4y(2)

= 4xy + 8y

3y(7x+2)

= 3y(7x) + 3y(2)

= 21xy + 6y

Answer:

see below

Step-by-step explanation:

1. a = 18, 2. n = -19, 3. x = -17, 4. v = -6, 5. a = 9, 6. x = -2, 7. k = -4,  8. m = -19

9. n = 3, 10.  a = -7, 11. n = -5, 12. n = -6, 13. x = -1/3, 14. m = 2/3 15. m = -9.8

16. n = 7.9, 17. x = 0, 18. b = 2, 19. v = -8, 20. b = -4, 21. n = 3, 22. p = 3.3

The number of new cars purchased in a city can be modeled by the equation C=20t to the 2nd power, where C is the number of new c
Allisa [31]

Answer:

1998 + 5\sqrt{30}

Step-by-step explanation:

Set up the equation:

Since C(t) gives the number of cars purchased in the t-th year after 1998, then make the number of cars equal to 15 000 and solve for t - the year:

20t^2 = 15000

t^2 = 750

t = \sqrt{750} = \sqrt{10} \cdot \sqrt{25} \cdot \sqrt{3} = 5\sqrt{30}

The year will be simply 1998 + 5 \sqrt{30}
