Answer:

$(2x(5x+1))/(4x-1)$

Step-by-step explanation:

Given expression:

$((4x^3-12x^2)/(4x^2+7x-2))/((2x^2-6x)/(5x^2+11x+2))$

Consider the numerator and the denominator separately.

Numerator:

$(4x^3-12x^2)/(4x^2+7x-2)\n \n=(4x^2(x-3))/(4x^2+8x-x-2)\n \n=(4x^2(x-3))/(4x(x+2)-(x+2))\n \n=(4x^2(x-3))/((x+2)(4x-1))$

Denominator:

$(2x^2-6x)/(5x^2+11x+2)\n \n=(2x(x-3))/(5x^2+10x+x+2)\n \n=(2x(x-3))/(5x(x+2)+(x+2))\n \n=(2x(x-3))/((x+2)(5x+1))$

The whole expression:

$((4x^3-12x^2)/(4x^2+7x-2))/((2x^2-6x)/(5x^2+11x+2))\n \n \n=((4x^2(x-3))/((x+2)(4x-1)))/((2x(x-3))/((x+2)(5x+1)))\n \n \n=(4x^2(x-3))/((x+2)(4x-1))\cdot ((x+2)(5x+1))/(2x(x-3))\n \n \n=(2x(5x+1))/(4x-1)$

A proportional relationship between two quantities is one in which the two quantities vary directly with one and other. If one item is doubled, the other, related item is also doubled.

So the answer would be C

But lets see the proof:
The first x and y ratio is 2:6 which equals 1:3
The second one is 4:12 which equals 1:3
The third one is 6: 18 which equals 1:3
The fourth one is 8: 24 which equals 1:3

Which means all 4 of the ratios are the same. So therefore the answer is C

A proportional relationship meaning that all the sets are proportional.

A) 2/6 = 0.33
5/8 = 0.625

So, A is a wrong answer.

C) 8/4 = 2
24/4 = 6

4/12 = 2/6
6/18 = 2/6

Therefore, we have a proportional relationship!

Answer:- C.

julian earns $13.50 per hour. His company deducts 23% of his pay each week for taxes. Julian uses the expression 0.77 ( 13.50h) to compute his earnings after taxes for the hours h he works. what will be his earnings after taxes, if he works 40 hour?

Answers

If Julian works 40 hours per week and you would like to know what are his earnings after taxes, you can calculate this using the following steps:

per one hour: 0.77 * (13.50 * 1h) = 0.77 * 13.50 = $10.395
per 40 hours: 0.77 * (13.50 * 40h) = 0.77 * 13.50 * 40 = $415.8

Result: His earnings after taxes will be $415.8.

for this problem, all you have to do is plug 40 into the equation given. when we do this we get .77(13.50*40). this simplifies 415.8, so he earns, after working 40 hours, $415.80
