Composite is a number that is NOT prime. So we want to find an odd perfect square that IS prime to be a counterexample.
√36 = Not odd
√49 = 7 Factors only 1 * 7 so it is prime
√81 = 9 Factors 1, 3, 9 composite
√225 = 15 Factors 1,3, 5,9,15, 25, 45, 75, 225 composite
Counterexample for 2∧n - 1 Is prime
2^6 - 1 = 64 - 1 = 63 NOT PRIME Factors are: 1, 3, 7, 9,21, 63
2^5 - 1 = 32 - 1 = 31 Prime
2^3 - 1 = 8 - 1 = 7 Prime
2^2 - 1 = 4 - 1 = 3 Prime
Answer:
x = 75/88 miles
or
x = 0.85227 (27 repeated) miles
Step-by-step explanation:
1 mile =1760 yards
x miles = 1500 yards
x = 1500 / 1760
x = 75/88
or
x = 0.85227 (27 repeated)
Answer:
The answer is A: 350 ≥ 125 + 15x
Step-by-step explanation:
The amount of money spent would need to be greater than or equal to the budget. $125 was already spent. You would then ADD the amount of canvas' you buy, x, times 15, the amount of $ per canvas. (15x).
Hope this helps.
