Expand the binomial (4x + 3y)3. the coefficient of the second term in the expansion of the binomial (4x + 3y)3

The coefficient is 144.

Step-by-step explanation:

We have the binomial:

The general formula for cubic binomials is:

Observation: if you solve that the result is the general formula. The same for  

Then we have:

The coefficient is the number before the variable, then the coefficient of the second term in the expansion of the binomial is 144.

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

42.4
