Name a combination of coins that is 65% of the value of a dollar. (SHOW LIST OF COINS MULTIPLICATION/ADDITION TO EQUAL 65%)**

2 quarters, a dime and a nickel

Step-by-step explanation: There are multiple ways to do this, but with a single dollar it would be 100(cents in a dollar) divided by the 65%. The 65% is just 65/1, which is 65 cents. Almost any coins that add to 65 cents will work.

answer: 20

step-by-step explanation:

answer:   x = 3 + √11     and     x = 3 - √11

step-by-step explanation:

x² - 6x + 9 = 11

(x - 3)² = 11

x - 3 = ±√11

    x = 3 ± √11

x = 3 + √11     and     x = 3 - √11
