For this case we have the following equation:


y ^ 2 + 7y = 18

Rewriting the equation we have:


y ^ 2 + 7y-18 = 0

Then, we must factor the equation:


We are looking for two numbers that are equal to 7 and multiplied equal to -18.


We have then:


(y + 9) (y-2) = 0

Answer:


An equation that could be used to solve y^2 + 7y = 18 by factoring is:


(y + 9) (y-2) = 0

at shop and shop ,shaquana buys 3 pounds of squash and 2 pounds of eggplants and pays $2.85.then ,evelyn buys 4 pounds of squash
Montano1993 [528]

Each pound of squash cost $0.49 while each pound of eggplant cost $0.69.

Let x represent the cost of each pound of squash and y represent the cost of each pound of eggplant.

3 pounds of squash and 2 pounds of eggplants cost $2.85. Hence:

3x + 2y = 2.85   (1)

4 pounds of squash and 5 pounds of eggplants cost $5.41. Hence:

4x + 5y = 5.41   (2)

Solving equation 1 and 2 simultaneously gives:

x = 0.49, y = 0.69

Each pound of squash cost $0.49 while each pound of eggplant cost $0.69.
