Answer:

- 8

Step-by-step explanation:

Given

(4 +4 x²)(3x² - 5)

Each term in the second factor is multiplied by each term in the first factor, that is

4(3x² - 5) + 4x²(3x² - 5) ← distribute parenthesis

= 12x² - 20 + 12x^{4} - 20x² ← collect like terms

= 12x^{4} - 8x² - 20

with coefficient of x² term being - 8

Alexis counted 16 commercials while watching 30 min of tv. At this rate, how many commercials would play in a day
Nat2105 [25]
<span>There are several information’s that are actually of immense importance, already given in the question. Based on these information’<span>s the answer to the question can be easily deduced.</span></span>We already know that 
24 hours = (24 * 60 ) minutes
               = 1440 minutes
Then
In 30 minutes the number of commercials shown =16
so 
In 1440 minutes the number of commercials shown = (16/30) * 1440
                                                                                    = 768
So the number of commercials shown in 24 hours is 768.

40 POINTSSS PLEASE HELPP!!

A) The inverse of the statement is the opposite. The statement stated that if two lines do not intersect, they are parallel. So, the opposite would be if two lines intercept, they are parallel. This inverse statement is false because, that is not true. Parallel lines mean they never intercept, not if they intercept its parallel.

b) Converse means to engage or explain, I think…so, the converse of the statement would be that yes, it is true that when two lines do not intercept then they are parallel. Because parallel lines never cross or meet, meaning they will NEVER ever have a crossing point.

c) the contrapositive of the statement would be: if two lines do not cross then they are parallel. If they do intercept, then they are not parallel. As simple as that. I think contrapositive means that…I looked what contrapositive means…so I think I’m right.

I hope this helps!! Or some at least. :)

Good luck!
