Which expression is equivalent to 36x2 − 25? (18x)2 + (−5)2 (18x)2 − (5)2 (6x)2 + (−5)2 (6x)2 − (5)2

The correct answer is last option (6x)² - (5)²

Step-by-step explanation:

It is given an expression in variable x,

36x² - 25

To find the equivalent expression of  36x² - 25

We have, 36 = (±6)²  and 25 = (±5)²

36x² - 25 can be written as,

36x² - 25 = (±6x)² - (±5)²

From the given options we get the correct answer is last option

(6x)² - (5)²

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
