Answer:
Step-by-step explanation:
x⁸ - 6561 = x⁸- 3⁸ = (x⁴)² - (3⁴)²
= (x⁴ + 3⁴) (x⁴ - 3⁴) {a² - b² = (a+b)(a-b); here a =x⁴ and b= 3⁴ }
= (x⁴ + 3⁴) ( [x²]² - [3²]²) {here a =x² and b = 3²}
= (x⁴ + 3⁴) (x² + 3²) (x²- 3²)
= (x⁴ + 81) (x² + 9) (x + 3) (x-3)
Answer:
Brent
Step-by-step explanation:
More numbers = More combinations
440/8 will get you how many miles Sarah travel in 1 hour.
But Sarah travels 55 miles in 1 hour.
Sarah can travel 330 miles in 6 hour.
Answer:
(-1,-2) is correct.
Step-by-step explanation:
To find the solution of both linear graphs, you can do by finding the intercept of both graphs.
Both graphs intersect each others at x = -1 and y = -2.
Focus on x = -1 then look down and you will see that both graphs intersect at y = -2.
Thus:-
You're correct!
