The solution of the equation 3(x+3)=12
vaieri [72.5K]

Answer:

1

Step-by-step explanation:

3(x + 3) = 12

Multiply 3 by both numbers in the parentheses.

3x + 9 = 12

Subtract 9 from both sides of the equation.

3x = 3

Divide 3 from both sides of the equation.

David borrowed $30,000 to start a business. Four years later, he repaid the $30,000 along with an interest of $1,260. What was t
torisob [31]

Answer:

1.05%.

Step-by-step explanation:

If an amount of money, P, called the principal, is borrowed for a period of t years at an annual interest rate r, the amount of interest, I, is given by

I=PrtwhereIPrt=interest=principal=rate=time

The following information is given.  

IPt=$1,260=$30,000=4 years

Substituting the given information into the simple interest formula and solving for r gives

I1,2601,260=Prt=(30,000)(r)(4)=120,000r

Dividing both sides by 120,000 and then converting to a percent, we have

r=1,260120,000=0.0105=1.05%

Thus, David's annual interest rate was 1.05%.

Which expression is equivalent to (image attached)
Monica [59]
<h2>Hello!</h2>

The answer is:

B. x(7x^{2}-3x+9)-3(7x^{2}-3x+9)

<h2>Why?</h2>

We are given a simplified expression and we are asked to know which of the given options is equivalent to the simplified expression, so, we need to apply the distributive property in order to find the correct choice.

The distributive property states that:

(a+b)(c+d+e)=a(c+d+e)+b(c+d+e)=ac+ad+ae+bc+bd+be

So, if we are given the following expression:

(x-3)(7x^{2}-3x+9)

Then, we need to apply the distributive property in order to find the equivalent expression:

(x-3)(7x^{2}-3x+9)=x(7x^{2}-3x+9)-3(7x^{2}-3x+9)

Hence, the correct option is:

B. x(7x^{2}-3x+9)-3(7x^{2}-3x+9)

Have a nice day!
