5 dimes 10 nickels is the answer
Answer:
10+2+4x
Step-by-step explanation:
its very simple but still right because 10 and 2 is 12 and well 12+4x is the thing you want to have the same as
5 + (n - 1)²
5 + (n - 1)(n - 1)
5 + (n² - n - n + 1)
5 + (n² - 2n + 1)
n² - 2n + 1 + 5
n² - 2n + 6 = 0
n = <u>-(-2) +/- √((-2)² - 4(1)(6))</u>
2(1)
n = <u>2 +/- √(4 - 24)</u>
2
n = <u>2 +/- √(-20)
</u> 2
n = <u>2 +/- 2i√(5)</u>
2
n = 1 <u>+</u> i√(5)
n = 1 + i√(5) n = 1 - i√(5)
The answer is equal to B.

The circumference has the formula 2xπxr, where r is the radius;
We have 47 feet = 2xπxr;
Then, r = 47 / (2π) ;
But, π ≈ 3.14;
Finally, r ≈ 47 / 6.28;
r ≈ 7.48 feet;
Step-by-step explanation:
10% more = 110% of the number.
110% of the number = 132
100% of the number = 132 * (10/11) = 120.
The number is 120.
