3 0

Answer:

(2x-3)(2x+3)

Step-by-step explanation:

4x^2-0x-9

(4x^2-9)

(2x)^2 - (3)^2

We recognize that this is the difference of squares a^2 - b^2 = (a-b)(a+b)

(2x-3)(2x+3)

Consider the two functions:
Alik [6]

Answer:

Step-by-step explanation:

1, Find (g-f)(x)

we know (g-f)(x) = g(x) - f(x) = ( 5x -2) -( 2x^2 +3x +6)

= 5x -2 - 2x^2 - 3x - 6

= -2x^2 + 2x -8

So the function (g-f)(x) = - 2x^2 + 2x - 8

2, Find (fg)(x)

we know that (fg)(x) = f(x) * g(x)

= (2x^2 +3x +6 ) *( 5x -2)

= 5x* (2x^2 +3x +6 ) - 2*(2x^2 +3x +6 )

= 10x^3 + 15x^2 +30x -4x^2 -6x - 12

= 10x^3 + 11x^2 + 24x - 12

The answer is (fg)(x)= = 10x^3 + 11x^2 + 24x - 12

The population of a certain country is approximated by the following equation, where x is the number of years since 1980 and P i
saveliy_v [14]

Answer:

235

Step-by-step explanation:

The population equation is given as P= 2.726x + 126.189

-To find the number of years since 1980, we subtract the start year from the current year(2020):

X=2020-1980=40

We substitute the x value in the population equation to find the current population:

P=2.76x+126.189 but x=40

P=2.76(40)+126.189=235.229

Rounding off then the population in the current year is 235

Helppppp plsssssss- :
rewona [7]

Answer:

Q4 = 4 || Q5 = 6 2/3 || Q6 = 4 4/7 || Q7 = 10 || Q8 = 3 1/3 || Q9 = 4 1/2

Step-by-step explanation:

In order to divide fractions, you just have to turn it into multiplying!
Flip the second fraction in the number sentence and then multiply!

Example: 5 divided by 6/7

Keep 5 as it is. Flip 6/7 to 7/6. 5 x 7/6 = 35/6

Now, simplify it! Simplifying is very simple. You just have to divide until they can't be divided anymore.

35/6 simplified = 5 5/6.

Reason:

How many 6's are in 35? 5 R: 5

So, then it would be 5 5/6.

Hope this helped and this was correct! If you have any more questions, I'll be here to answer them!
