Which expression is equivalent to the expression below?(6c^2+3c/-4c+2)/(2c+1/4c-2)

algol [13]

Answer:

-3c

Step-by-step explanation:

The given expression is:

$\frac{\frac{6c^{2}+3c}{-4c+2}}{\frac{2c+1}{4c-2}}$

We need to simplify this expression. The rational expression in the denominator can be multiplied to numerator by taking its reciprocal as shown below:

$\frac{\frac{6c^{2}+3c}{-4c+2}}{\frac{2c+1}{4c-2}} \\\\ =\frac{6c^{2}+3c}{-4c+2} \times \frac{4c-2}{2c+1}\\\\=\frac{3c(2c+1)}{-(4c-2)} \times \frac{4c-2}{2c+1}\\\\ =-3c$

Thus, the given expression in simplified form is equal to -3c

How do i solve this? 7 < 3 - 2x It's linear inequalities

Natasha2012 [34]

Hello from MrBillDoesMath!

Answer:

x < -2

Discussion:

7 < 3 - 2x => Add 2x to both sides

7 + 2x < 3 - (2x - 2x) => As 2x -2x = 0

7 + 2x < 3 => Subtract 7 from both sides

(7-7) + 2x < 3 - 7 => As 7-7 = 0 and 3-7 = -4

2x < -4 => Divide both sides by 2

x < -4./2 = -2

Thank you,
