Describe the steps for simplifying the expression 2x + 3 + 5x – 15.​

Step-by-step explanation:

2x+3+5x-15

I can start off by combining like terms (2x and 5x with 3 and -15)

2x+5x+3-15

and my new equation will be 7x-12. Since they are not like terms (15 does not have x so I can't continue solving), 7x-15 will be my final answer.

Group and add the x coefficients (factoring)

Add the other numbers: 3 and -15

2x + 3 + 5x – 15 = 2x + 5x + 3 – 15 = 7x - 12

Step-by-step explanation:

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.
