Answer:
7 Quarters and 3 dimes
Step-by-step explanation:
You have to find how many quarters (0.25) and dimes (0.10) are in $2.05. There are 7 quarters, which will add up to $1.75. You can't have 8 quarters because then you would have 2 dollars, and there wouldn't be enough for a dime, there would only by 5 cents left, or a nickle. Then, you find out how many nickels you need, which is 3.
.10x3=.30. 1.75+0.3=2.05.

Answer:
B
Step-by-step explanation:
Given
x² - 2x + 26 = 0 ← in standard form : ax² + bx + c = 0 : a ≠ 0
with a = 1, b = - 2, c = 26
Use the quadratic formula to solve for x
x = ( - (- 2) ± ) / 2
= ( 2 ± ) / 2
= ( 2 ± ) / 2
= ( 2 ± 10i ) / 2
= 1 ± 5i
Solutions are x = 1 + 5i or x = 1 - 5i → B
