(10.4)2 = to the second power is the 2

10.4^2 = 108.16

Step-by-step explanation:

10.4^2 = 10.4 * 10.4

10.4 * 10.4 = (10 * 10.4) + (0.4 * 10.4)

(10 * 10.4) + (0.4 * 10.4) = (104) + (4.16)

(104) + (4.16) = 108.16

10.4^2 = 108.16

good luck

let x be the money she spent so that she can earn the free t-shirt.

since, she already spent $112.49

⇒

also, as per the statement: jennifer must spend $250 or more in order to qualify for a free t-shirt at the store.

then,

we have an inequality i.,e

subtract 112.49 from both sides we get;

therefore, $137. 51 more money does jennifer need to spend so that she can earn the free t-shirt
