<u>Answer</u>
9+√14
<u>Explanation</u>
To Rationalize the denominator of 5-√7/9-√14.
To rationalize this we multiply both the denominator and denominator by the conjugate of the denominator.
The denominator is 9-√14 and its conjugate is (9+√14).
(5-√7)/(9-√14) = (5-√7)(9+√14)/(9-√14)(9+√14)
= (5-√7)(9+√14)/(9²-14)
= (45 + 5√14 - 9√7 - √98)/(81-14)
= (45 + 5√14 - 9√7 - √98)/67
= (45 + 5√14 - 9√7 - 7√2)67
This is the rationalized expression.
The denominator is (9-√14) and its conjugate is (9+√14).
The answer is the third one
Your answer is:
B. x<<span>−<span>10</span></span>
We first know that 66 as a decimal is well 66. Now, 2/3 as a decimal would be 66.666666 and so on on. Therefore, 66 and 2/3 as a decimal is 66.66666 and so on.
Well 2x plus 7x equals 9x
6+3 equals 9
so 9x-9
