Solve this equation X^2+8x-13=0

x² + 8x - 13 = 0

x = -4 + √29   -> x = 1.38516

x = -4 - √29   -> x = -9.38516

step-by-step explanation:

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
