A clothing store had a rectangular clearance section with a length that is twice the width w. during a sale, the secrion is expanded to an area of 2w^2 + 19w+35ft^2. find the amount of the increase in the length and width of the clearance section

The length is increased by 5 feet and width is increased by 7 feet.

Step-by-step explanation:

Given:

Length of section is twice the width.

During sale the section is expanded to an area =

To find increase in length and width.

Solution:

Let the length of the section be =

width of the section =

Expression for area :

Factoring:

So, area of the section after increase can be given as

We know that length is twice the width, which means:

Substituting the value of in the factored expression of area.

Since area of triangle is product of length and width, so we have:

New length of section =

New width of the section =

Thus, length is increased by 5 feet and width is increased by 7 feet.

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.
