A + 3A = 120
4A = 120
A = 30
B = 90
Answer:
-4, 2, 3
Step-by-step explanation:
Centre: (-4,2)
Radius: 3
(x - h)² + (y - k)² = r²
(x - -4)² + (y - 2)² = 3²
(x + 4)² + (y - 2)² = 9
<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).
