The correct answer is option C which is 3.

<h3>What is an expression?</h3>

Expression in maths is defined as the collection of the numbers variables and functions by using signs like addition, subtraction, multiplication and division.

The given expression will be solved as follows:-

E = 3( x² +6 -3x)- ( 2x² - 8 ) +3(x² + 4x )

E = 3x²+18-9x-2x²+8+3x²+12x

E= 4x² +3x+8

We can see the coefficient of x is 3.

Therefore the correct answer is option C which is 3.

ryzh [129]

Answer:

The total cost of the lunch including the tip is $15.21.

Step-by-step explanation:

To find the total cost of the lunch including the tip, first, you need to calculate 17% of the price of the lunch as the statement indicates that that is the tip Joseph leaves the waiter:

$13*17%=$2.21

$13+$2.21=$15.21

According to this, the answer is that the total cost of the lunch including the tip is $15.21.

lana [24]

$\frac{7}{9} = 0.777777777777777...$

To get a percentage, you need to first round the decimal to the hundreths place. Whenever you have a number greater than 5, you round up.
Therefore, you can round it to 0.78.
Now to get the percentage you multiply it by 100.

$0.78*100 = 78$

This shows your answer is (c) 78%.
