Factorize the following:x^2+3x-40

(x-5)(x+8)

x = 5

x = -8

Step-by-step explanation:

x^2+3x-40

Factorise

Two numbers that when added together gives +3 and when multiplied together gives -40.

The two numbers are +8 and -5

+8-5=+3

+8 X-5=-40

Hence, we substitute this two numbers with +3 in the equation above

x^2+8x-5x-40

We group into bracket

(x²+8x)-(5x+40)

In the first bracket, x is common while 5 is common in the second bracket

x(x+8)-5(x+8)

(x-5)(x+8)

x-5=0 x=5

x+8=0 x=-8

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.

$650 per month plus utilities

step-by-step explanation:

just based on the info you gave, it would seem more cost effective to rent at $650 per month plus utilities.   if utilities are, in fact, $150 per month, your monthly living costs would be $800 as opposed to the other option of $825.
