I need to find the value of x. I also need to show my work so if anyone answers this I need to know what the work is. Thank you!

x = 8

Step-by-step explanation:

Given a tangent and a secant from an external point to the circle, then

The square of the tangent is equal to the product of the secants external part and the whole secant, that is

x² = 4(4 + 12) = 4 × 16 = 64 ( take the square root of both sides )

x = = 8

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

answer: 4 (:
