X= y +3 = 1
3x - 2y = 2
so answer is A
Answer:
31
Step-by-step explanation:
To rationalise 7 + 3 , multiply by its conjugate
The conjugate of 7 + 3 is 7 - 3 , then
(7 + 3)(7 - 3) ← expand using FOIL
= 49 - 21 - 21 - (3)²
= 49 - 18
= 31
Yes. It would be a scalene triangle.
However, a right triangle cannot have those lengths (because if we inputted the values into the Pythagorean Theorem, it wouldn’t be a true equation).
Hope this helps! (:
