3, if you do the y^2-y^1/x^2-x^1 you will get 3/1 which will be simplified to 3.
<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).
Jus go a thru z and you’ll be fine
Monday= 13.45
Tuesday=9.5
wednesday/Friday= x/3
1st. you add Monday and Tuesday
2nd. you subtract the total 42.6 with added numbers of step one
3rd. finally you divided the total of step 2 by 3
finally you shall receive your answer.
