Which expression is equivalent to: (x +9)(x+3)

Mathematics

Serga [27]3 years ago

Answer:

C

Step-by-step explanation:

To solve use the FOIL method, First, Outside, Inside, Last. This means to multiply the first terms, the ones on the outsides, the ones on the insides, and finally the last ones.

First, multiply x*x= x^{2}

Then, multiply x*3= 3x

Next, multiply 9*x= 9x

Finally, multiply 9*3= 27

To simplify put all of the products together, x^{2}+3x+9x+27, then add like terms x^{2}+12x+27, so the answer is C.

Help plz I’m not good at this
Natalka [10]

Answer:

<u>The correct answer is A. 1/8</u>

Step-by-step explanation:

<u>Let's solve (1/3 * 9/16) / 1 1/2 = x</u>

(1/3 * 9/16) / 1 1/2 = x

9/48 / 1 1/2 = 9/48 * 2/3 = 18/144

18/144, we can simplify dividing by 18 at the numerator and the denominator, this way:

x = 18 ÷ 18/ 144 * 18 = 1/8

<u>The correct answer is A. 1/8</u>

If pr is 3x+14 and qr 7x-10 what is x
mr Goodwill [35]
Start the equation by putting the equations equal to each other 3x+14=7x-10
Next +10 on both sides
3x+14=7x-10
+10 +10
You are left with 3x+24=7x
because the 10's canceled each other out.
Next -3x on both sides
3x+24=7x
-3x +3x

You are left with 24= 10x
because like before the 3's canceled each other out
Now you will divide both sides by 10

24=10x
---- -----
10 10

2.4= X is the answer!

Suppose you roll not die. Find the Probability of not rolling an even number
irina [24]
I think you mean roll a die. To do this you would find the number of non-even numbers and divide that number by the total amount of numbers on the die. On a normal six-sided die these numbers would be 1,3,and 5, so your probability of not rolling an even number would be 50%

Lena [83]

The answer to the question will be 0. 3 Modifying Above 18 with bar

<h3>What will be the decimal expansion of 7 over 22? </h3>

When we divide 7 by 22 we will get 0.3181818..........

Here 3 is not repeating but 18 is repeating again and again

So it is a Non-terminating repeating number

Thus the answers to the question will be 0. 3 Modifying Above 18 with bar
