Yes so for example starting at number 10 (x to the second power = 49) x would equal 7 because 7 to the second power is 49. (7x7= 49) Your answer is x=7.

Number 2 is x = 10 because 10 x 10 = 100

Write this expression so that its denominator, if any, is a positive integer.<br> 2/(3+sqrt(7))
Tanzania [10]

Answer:

The Answer is 3 - sqrt7

Step-by-step explanation:

2/3 + sqrt7   the starting equation

You multiply it by the conjugate which is 3 - sqrt7

= 2(3 - sqrt7) / (3 + sqrt7) (3 - sqrt7)  the equation after you multiply by 3 - sqrt7

(3 + sqrt7) (3 - sqrt7) = 2

= 2(3 - sqrt7) / 2    the equation after you simplify (3 + sqrt7) (3 - sqrt7)

Divide out the 2's

= 3 - sqrt7/1    the equation after you divide out the 2's

= 3 - sqrt7  is THE ANSWER

<h3>Answer:  1728 dollars</h3>

==========================================================

Explanation:

1 yard = 3 feet

We'll divide by 3 to convert from feet to yards

  • 27 feet = 27/3 = 9 yards
  • 18 feet = 18/3 = 6 yards

The basement is 9*6 = 54 square yards in floor area.

At $32 per square yard, the total cost to carpet the floor is 32*54 = 1728 dollars.
