Answer:
24
Step-by-step explanation:
Since the ladder, wall, and ground form a right triangle, you can use this formula:
A squared + B squared = C squared
A = 7 feet
C = 25 feet
B = distance the ladder will reach
49 + B squared = 625
B squared = 625 - 49
B = square root of 576
B = 24 feet
Answer:
Step-by-step explanation:
Given:
Area = 3x^3 - 16x^2 + 31x - 20
Base:
x^3 - 5x
Area of trapezoid, S = 1/2 × (A + B) × h
Using long division,
(2 × (3x^3 - 16x^2 + 31x - 20))/x^3 - 5x
= (6x^3 - 32x^2 + 62x - 40))/x^3 - 5x = 6 - (32x^2 - 92x + 40)/x^3 - 5x = 2S/Bh - Ah/Bh
= 2S/Bh - A/B
= (2S/B × 1/h) - A/B
Since, x^3 - 5x = B
Comparing the above,
A = 32x^2 - 92x + 40
2S/B = 6
Therefore, h = 1
