Answer:
3 ln(x − 1) − 3/(x − 1) + C
Step-by-step explanation:
∫ 3x / (x − 1)² dx
3 ∫ x / (x − 1)² dx
If u = x − 1, then x = u + 1, and du = dx.
3 ∫ (u + 1) / u² du
3 ∫ (1/u + 1/u²) du
3 (ln u − 1/u + C)
3 ln u − 3/u + C
Substitute back:
3 ln(x − 1) − 3/(x − 1) + C
She could measure the next length to the left or right and she will have all 4 sides because a rectangle has 2 sets of equal sides.
50÷8.5 = 5.88 but since we can’t have .88 of a person the answer would be five T-shirts
The correct answer would be C
