Joe is building a post for his mailbox. to find the correct dimensions, he needs to expand this expression: (x-3) (x-9) (x-4) select the equivalent expression written in the format ax3(cubed) + bx2(squared) +cx+d

Step-by-step explanation:

Given:

The expression to expand is given as:

Let us expand the first two binomials of the given expression using FOIL method.

The FOIL method states that:

Now, let us multiply the result with the remaining binomial. Multiplying each term of the trinomial with each term of the binomial, we get:

Therefore, the equivalent expression after expanding is given as:

plants store their excess carbohydrate in the form of starch so that it could be used as energy source later on. the excess carbohydrate is converted into starch in the plastid i.e. chloroplast & this process occurs in the presence of sunlight. it is an insoluble polymer of glucose which gets stored in cell organelles named as amyloplasts. in some plants, starch is also stored in roots and embryos.

the answer is simply just 6n add the two together as they have an n
