BRAINLIEST TO CORRECT ANSWER Explain how you would apply exponent rules to evaluate for the value of (x³/x)² if x = 1/2?

225x²+4=0

225x²=0-4

225x²=-4

x²=-4/225

x=±√-4/225

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

option (b) is correct

step-by-step explanation:

to find the solution of this system, we need to convert it into reduced row-echelon form. we have,

after applying row operations r2 -> r2/2 and r3 -> r3/3, we get,
