Answer:

= 6x^3-33x^2+45x-6

Step-by-step explanation:

= (3x+-6)(2x^2+-7x+1)

= (3x)(2x^2)+(3x)(-7x)+(3x)(1)+(-6)(2x^2)+(-6)(-7x)+(-6)(1)

= 6x^3-21x^2+3x-12x^2+42x-6

= 6x^3-33x^2+45x-6

Franklin saved money to buy art supplies

Nikolay [14]

<u>Question</u>:

Franklin saved money to buy art supplies. He used 1/5 of his savings to buy brushes. He used 1/2 of his savings to buy paint. What fraction of his savings does he have remaining?

Answer:

Franklin had $\frac{3}{10}$ of his saving left.

Step-by-step explanation:

Amount used to buy brushes = 1/5

Amount used to buy paint = 1/2

Solution:

Let the remaining amount be x

then ,

x = 1- (amount used on buying brushes + amount used for buying paints)

$x = 1- (\frac{1}{5} + \frac{1}{2})$

$x = 1- (\frac{2+5}{10})$

$x = 1- (\frac{7}{10})$

$x =\frac{10-7}{10}$

$x =\frac{3}{10}$

Answer:

916.1 cm^3

Step-by-step explanation:

1) find the radius of the cylinder:

radius = dimater / 2 = 7,3 / 2 = 3.65 cm

2) find the base area of the cylinder:

base area = radius^2 x 3.14 = 3.65^2 x 3.14 = 41.83265 cm^2

3) find the height of the cylinder:

height = 7.3 x 3 = 21.9 cm

4) find the volume

V = base area x height = 41.83265 x 21.9 = 916.135035 cm^3

5) round to nearest tenth:

916. 1 cm^3

Faron wants to paint the four walls in his bedroom. The room measures 12 ft long, 10 ft wide and 8 ft high. There are two doors

Rainbow [258]

Answer:

319 square feet.

Step-by-step explanation:

The walls of the room (the ones on the long side) have an area of 12 x 8 = 96 square feet each one. Thus, their area is 96 x 2= 192 square feet.

The other two walls have an area of 10 x 8 = 80 square feet each one. Thus, their area combined is 80 x 2 = 160 square feet.

Therefore, we have that the total area of the four walls is

192 +160 = 352 square feet

However, we have a door and a window that won't be painted.

The area of the door is: 3 x 7 =21 square feet

The area of the window is 3 x 4 = 12 square feet

Thus, the total amount of area that won't be painted is

21 + 12 = 33 square feet.

So we are going to take the total area minus the area that won't be painted to know the total area that Faron will pain:

352 - 33 = 319 square feet.

Thus, she will paint 319 square feet
