If (x-2) is a factor of xsquare+3x+5a find the value of a

a = -2

Step-by-step explanation:

(x-2) (x+b) = x² + (b-2) x - 2b = x² + 3x + 5a

b-2 = 3

b = 5

5a = - 2b = - 10

a = -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
