Answer:
- (7 + √10) / 3.
Step-by-step explanation:
You simplify this by multiplying the numerator and denominator by the conjugate of the denominator which, in this case, is √2 + √5.
(√2 + √5)(√2 + √5) 2 + 2√10 + 5 7 + 2√10
---------------------------- = ------------------- = -------------
(√2 - √5)(√2 + √5) 2 - 5 -3
Answer is - (7 + √10) / 3.
Answer:
2x+7
Step-by-step explanation:
3x +(-x) = 3x - x, so it's 2x
12 + (-5) is the same situation, just being 12 - 5, so it's 7.
putting them together leaves you with 2x+7
