Step-by-step explanation:

Given

(2x + 3 )² - (2x + 3) (x - 5)

= 4x² + 6x + 9 - ( 2x (x - 5) + 3(x - 5 ))

= 4x² + 6x + 9 - ( 2x² - 10x + 3x - 15 )

= 4x² + 6x + 9 - 2x² + 10x - 3x + 15

= 2x² + 13x + 24

Hope it will help :)

What is probability?

Probability is the branch of mathematics concerning numerical descriptions of how probably an event is to do, or how likely it's that a proposition is true. The probability of an event is a number between 0 and 1, where, roughly speaking, 0 indicates impossibility of the event and 1 indicates certainty.( note 1)( 1)( 2) The advanced the probability of an event, the more likely it's that the event will do. A simple illustration is the tossing of a fair( unprejudiced) coin. Since the coin is fair, the two issues(" heads" and" tails") are both inversely probable; the probability of" heads" equals the probability of" tails"; and since no other issues are possible, the probability of either" heads" or" tails" is1/2( which could also be written as0.5 or 50).

Y varies directly with x. If x=6 when y=30, determine y when x=8.
kondaur [170]

Answer:

Y=40

Explanation:

Due to the nature of both X and Y varying directly, you can view the problem as a proportion. If x=6 and y=30, that must mean that when x=8  y must equal 40.

6:30 = 8:40

or

30/6= 5

Y/8= 5

Because they vary directly they are equivalent, and so multiply 8 by 5 and get 40.
