Factor completely 7x^5-21x^4+14x^3

7x³ (x-2) (x-1)

Step-by-step explanation:

7x⁵-21x⁴+14³

= 7x³ (x²-3x+2) < factor out the gcf

= 7x³ (x-2) (x-1)

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

the answer will be b x² +x-1
