3x2 + 5x2 + 2x
3x5 + 5x3 + 2x2

Answers

Answer:

(A) 3x^3+5x+2

Step-by-step explanation:

To Simplify:  The quantity 3 times x to the 4th power plus 5 times x to the 2nd power plus 2 times x all over x.

Solution: The given statement can be easily rewritten as:

The quantity 3 times x to the 4th power=3x^4,

5 times x to the 2nd power=5x^2 and

2 times x =2x

Thus, according to the statement, the expression can be written as:

(3x^4+5x^2+2x)/(x)

⇒3x^3+5x+2

which is the required simplified expression.

Thus,option A is correct.

Flve tickets to a carnlval cost $45. How much would seven
tickets cost?

Answers

Answer:

$63

Step-by-step explanation:

In order to solve this problem, we need to find the unit price, which is the price per 1 ticket in this case. To find this, we need to divide $45 by 5 because each ticket is the same amount: $45 / 5 = $9. So each ticket is $9.

Now, we need to find how much 7 tickets would cost. To do this, multiply the $9 / ticket by 7 tickets: $9 * 7 = $63.

This, 7 tickets would cost $63.

Hope this helps! God Bless u!!!

Answer:

63

Step-by-step explanation:

because each ticket is $9 each
