Select all of the answers below that are equivalent to T = {Tinkey-Winky, Laa-Laa, Dipsy, Po}
{clock, carrots, bracelet, sidewalk, camera}
{thermostat, bookmark, candle}
{thermometer, fridge, rusty nail, deoderant}
O{credit card, face wash, tweezers, shovel}
{ring, floor, rubber band, spoon, bread, clock}
{clothes, glass, car, greeting card}

Step-by-step explanation:

The options that will be equivalent to T will have to be the options that have the same Cardinality as T. Cardinality refers to the number of elements in a set and in the set T, there are 4 elements being Tinkey-Winky, Laa-Laa,  Dipsy, Po so the Cardinality is 4.

The equivalent sets would therefore be sets with a cardinality of 4 as well and those are;

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
