Answer:

Step-by-step explanation:

Hello!

(x + 1)(x + 3) + (x + 2)(x + 4)

x*x = x²

x*3 = 3x

1*x = x

1*3=3

x*x=x²

x*4 = 4x

2*x= 2x

2*4 = 8

x²+3x+x+3+ x² + 4x+ 2x+  8=

2x² + 10x+ 11

Sally works 40 hours a week and makes $30 an hour, but her kids are in child care each day and the day care center charges her $
Lapatulllka [165]

Answer:

Sally will earn $21.25 per hour after she removes day care charges from her total earnings.

Step-by-step explanation:

Hey there!

Let's start by solving for how much money that Sally earns per week.

To find this value, we will find the product of 40 hours per week and 30 dollars per hour.

40\times30=1200

We now know that Sally makes $1,200 a week without deducting the daycare charges per day.

However, we know we need to deduct 70 dollars for each day that Sally works. Since she works for five days a week, we will find the product of 70 dollars per week and five days a week.

70\times5=350

Therefore, the day care charges $350 per week.

Finally, we need to subtract the day care charges from the amount of money that Sally earns to find how much she actually makes in a week.

1200-350=850

Therefore, for forty hours of work that Sally works each week, she earns $850.

However, we are not done. The question asks us to find how many dollars <u>per hour</u> does she actually make? Therefore, we need to find the quotient of 850 dollars and 40 hours per week.

\displaystyle \frac{850}{40}=21.25

Therefore, Sally earns $21.25 each hour after deducting day care costs.

kvasek [131]

Answer:

Joseph's present age=3 yrs

David's present age=9 yrs

Step-by-step explanation:

Let Joseph's present age be x.

David's present age=3x

__________________

Ater 3 yrs,

Joseph's age=x+3

David's age=2(x+3)

Also, we can add 3 to David's present age to get age After 3 yrs. So, David's age after 3 yrs would also be 3x+3.

Now, balance them.

3x+3=2(x+3)

3x+3=2x+6

x=3

D"s prsent age=9

J's present age=3

The product of 6 and a number less than 20
Lady bird [3.3K]

Answer:

I'm assuming that this is supposed to be in algebraic expression form.

Step-by-step explanation:

The <em>product of 6 and a number</em> is expressed as <em>6x.</em> So the expression of 6x less than (use minus symbol) 20, should be written as 6x - 20.

Hope it helps.
