What 2 numbers multiply to -14 and add to -5

-7*2 = -15

-7 +2 = -5

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

Using the zero product property

x-7 =0   x+2 = 0

x = 7      x= -2

Answer:

b. Borrow the money for the down payment and pay it back later

Step-by-step explanation:

Yvonne has a goal of buying a brand new home within a year.

She's afraid that she will be unable to save the money that she needs for a down payment.

The following should not be part of Yvonne's plan for achieving her goal of buying a home-

b. Borrow the money for the down payment and pay it back later

She can delay buying the house for a few months so she can save more money. She can also adjust her budget to save more. Also she can take a few other jobs to earn more and save more.

The only thing she should not consider is borrowing money.

In this way she will have to pay double debts. One to the lender and the other to the bank for home loan. Borrowing money will create more difficulties for her, so she should not so that.
a. Delay buying home for a few months

The expression 1/2 times(4+8) represent the number of hours Mrs nakos work that last week of school.evaluate the expression to find the number of hours she works that week

Answers

The expression\( (1)/(2) * (4 + 8) \)represents the number of hours Mrs. Nakos worked during the last week of school. When expression evaluated, it equals 6 hours. So, Mrs. Nakos worked 6 hours that week.

To find the number of hours Mrs. Nakos worked during the last week of school, you can evaluate the expression \( (1)/(2) * (4 + 8) \) step by step:

1. Start by evaluating the expression inside the parentheses:

\(4 + 8 = 12\)

2. Now, you have the expression\( (1)/(2) * 12 \). To calculate this, multiply 12 by
\( (1)/(2) \) since dividing by 2 is the same as multiplying by \( (1)/(2) \):
\( (1)/(2) * 12 = 6\)

So, Mrs. Nakos worked 6 hours during the last week of school.

The expression \( (1)/(2) * (4 + 8) \) represents the number of hours worked, and when evaluated, it equals 6 hours. Therefore, Mrs. Nakos worked 6 hours that week.
