Solve the quadratic formula <br> 2x^2+9x=-7
andriy [413]

Answer:

Step-by-step explanation:

2x² + 9x = -7

2x² + 9x + 7 = 0

When we multiply we should get 2*7 = 14 and when we add we should get 9. Find the factors of 14 ---> 1,2,7,14. Factors are 2,7 as when we multiply we get 14 and we we add, get 9

2x² + 2x + 7x + 7 = 0

2x( x + 1) + 7 (x + 1) = 0

(x  + 1)(2x + 7) = 0

Members of the wide city waters club pay $105 per summer season, plus $9.50 each time they rent a boat. Nonmembers must pay $14.
aalyn [17]
Set the equations equal to each other and solve for x (x being the number of boats)
105+9.50x=14.75x

Subtract the 9.50x from both sides
105=5.25x

Divide by 5.25
20=x

So a member and a nonmember have to rent a boat 20 times in order to pay the same amount of money
