Answer: 2 rational solutions
Step-by-step explanation:
When the discriminant, b² + 2a, is greater than 0, there are two real solutions. 49 is the perfect square of 7, so the solutions are also rational: plus and minus 7
2 over 7 =0,28
9/0,28=32,14

Answer:(d)
Step-by-step explanation:
Given
AB=AC
We can write
![\angle ABC=\angle ACB\ \quad \text{[angles corresponding to equal sides are equal]}](https://tex.z-dn.net/?f=%5Cangle%20ABC%3D%5Cangle%20ACB%5C%20%5Cquad%20%5Ctext%7B%5Bangles%20corresponding%20to%20equal%20sides%20are%20equal%5D%7D)

Answer:
x = ± 
Step-by-step explanation:
Given
mx² = f ( isolate x² by dividing both sides by m )
x² =
( take the square root of both sides )
x = ±
