Which expression is equivalent to the expression below? StartFraction 6 c squared + 3 c Over negative 4 c + 2 EndFraction divide

Triss [41]

Answer:

$\frac{-3c(2c + 1)}{2(2c - 1)}$

Step-by-step explanation:

We want to find the fraction that is equivalent to the fraction below:

Let us put the fraction above in a simpler form:

We can factorise the numerator with 3c and the denominator with -2.

$\frac{3c(2c + 1)}{-2(2c - 1)}\\\\= \frac{-3c(2c + 1)}{2(2c - 1)}$

Therefore, we see that $\frac{-3c(2c + 1)}{2(2c - 1)}$ is equivalent to $\frac{6c^2 + 3c}{-4c +2}$

A sculpture sits on a pedestal in the shape of a square prism. The side lengths of a base of the prism are 3 feet. The height of

german

Answer:

Total cost of covering the pedestal is $12.54.

Step-by-step explanation:

The pedestal is a square prism so top and bottom are of square shape.

Hence, we have here length = width

We know that the Total Surface Area of a Prism is:

$\text{Total Surface Area = } 2 (l\times w+ w \times h+ h \times l)$

Where l is length,

w is width and

h is height of prism

We know that here w = l = 3 feet

and h = 4 feet

Also, underside of pedestal is not to be covered.

The underside of pedestal is square type.

So,

$\text{Required Total Surface Area = } l\times w+ 2\times w \times h+2\times h \times l$

$\Rightarrow 3 \times 3 + 2 \times 3 \times 4 + 2 \times 3 \times 4\\\Rightarrow 9 + 24 + 24\\\Rightarrow 57\ ft^{2}$

Cost of cover per square foot = $ 0.22

Total cost of $57\ ft^{2}$ $\Rightarrow 0.22 \times 0.57 = \$12.54$

ohaa [14]

Answer:

Step-by-step explanation:

Same line = slope constant

(20-5)/(6-1) = (41-5)/(k-1)

3 = 36/k

k = 36/3

k = 12
