Answer:
a³ + b³
Step-by-step explanation:
Given
(a + b)(a² - ab + b²)
Each term in the second factor is multiplied by each term in the first factor, that is
a(a² - ab + b²) + b(a² - ab + b²) ← distribute both parenthesis
= a³ - a²b + ab² + a²b - ab² + b³ ← collect like terms
= a³ + b³
600 ft. This is because you travel 10 feet per second and there are 60 seconds in a minute. 10 x 60 =600
Answer:
1). x = 81
2). x = 84
Step-by-step explanation:
1). By applying geometric mean theorem in the given triangle,
56x = (18√14)²
56x = 4536
x = 
x = 81
2). By applying geometric mean theorem,
16x = (8√21)²
16x = 1344
x = 
x = 84
