Answer:

(x-2)(x+5)

Step-by-step explanation:

when factoring, our equation should be in this format: (x+__) (x+__) Then we have to find numbers that add up to 3 but multiply to -10 aka -2 and 5. -2+5=3 and -2(5)= -10

Answer:

1. x = 86

2. x = 31

3. x = 64

4. x = 29

Step-by-step explanation:

1. 2x + 8 = 180

-8 -8

2x = 180 (divide both sides by 2 to get x by itself)

2. 3x - 3 = 90

+ 3 +3

3x = 93 (divide both sides by 3 to get x by itself. you divide because 3x is multiplying and you have to do the reverse operation)

3. 2x -5 + x - 7 = 180 (you combine like-terms)

3x -12 = 180

+12 +12

3x = 192 (you divide by 3 on both sides)

4. x + 1 + x + 4 + x - 2 = 90 (combine like-terms)

3x + 3 = 90

-3 -3

3x = 87 (divide both sides by 3)

Answer:

1) 2x + 8 = 180

Take 8 to the right side.

2x = 172

Divide both sides by 2.

x = 86

2) 3x - 3 = 90

Take -3 to the right side.

3x = 93

Divide both sides by 3.

x = 31

3) 2x - 5 + x - 7 = 180

Combine like terms.

3x - 12 = 180

Take -12 to right side.

3x = 192

Divide both sides by 3.

x = 64

4)  x + 1 + x + 4 + x - 2 = 90

Combine like terms

3x + 3 = 90

Take 3 to right side.

3x = 87

Divide both sides by 3.

x = 29

Step-by-step explanation:

The rule which give the number of dots for the nth figure is [tex]= n^{2}[/tex]  or number of dots [tex]= n \times n[/tex], where n represents the number of figure.

A pattern is a repeated arrangement of numbers, shapes, colors and so on.

Let n represents the number of figure and m be the number of dots.

According to the given question.

We have some figures which is made up of dots with following some patterns.

In the given first figure i.e. for n = 1

The total number of dots is 1.

[tex]\implies m = 1[/tex]

In the second figure i.e. for n = 2

The number of dots gets increased and the counts of dots are 4.

⇒ [tex]m = 4[/tex]

[tex]\implies m = 2 \times 2[/tex]

In the third figure i.e. for n = 3.

The number of dots are 9

[tex]\implies m = 9[/tex]

[tex]\implies m = 3 \times 3[/tex]

Similarly, for the nth figure, the number of dots is given by

[tex]m = n \times n[/tex]

[tex]\implies m = n^{2}[/tex]  

Hence, the rule which give the number of dots for the nth figure is number of dots [tex]= n^{2}[/tex]  or  number of dots [tex]= n \times n[/tex], where n represents the number of figure.

Answer:

The volume of the ring is 12.6 [tex]cm^{3}[/tex]

Step-by-step explanation:

The volume of the ring will be equal to the increase in the volume after the ring is dropped. In order to find by how much volume increased we just subtract the volume before the ring was dropped from the volume that was recorded after the ring was dropped, and so we get...

(9.2 x 7 x 4.5) - (8.8 x 7 x 4.5) = 289.8 - 277.2 = 12.6 [tex]cm^{3}[/tex]

Answer 64

Step-by-step explanation: if x is 8 you do 8 x 9 which is 72. Then you do 2 x 4 which is 8. So now you have 72 - 8 which is 64.

Answer:

V = 8000in^3

Step-by-step explanation:

Replace s with 20 and solve the equation

Calculate 20 to the power of 3 and get 8000.

V=8000

Answer:

Step-by-step explanation:

Let’s break this apart.

Box= 12cm x 8cm x 6cm

Cube= 2cm x 2cm x 2cm

How many cubes fit in the box?

calculate the volume of the box. To do this, multiply the length by the width by the height (L x W x H)

12 x 8 x 6 = 576cm cubed

2. Calculate the volume of the cube. Once again we multiply L x W x H

2 x 2 x 2 = 8cm cubed

3. Next we divide the volume of the box by the volume of the cube

576 / 8 = 72 cubes

Therefore, it would take 72 cubes to fill a box.

Answer:

the volume of the whole shape is 676.35in^3

Step-by-step explanation:

the volume of the half cylinder is 196.35in^3

the formula used to find the volume is:

V = π * r² * h / 2

the volume of the cube is 480in^3

the formula used to find the volume is:

V = L*W*H

Answer:

64 ft²

Step-by-step explanation:

10 ft · 10 ft

100 ft²

[tex]A=\frac{bh}{2}[/tex]

6 · 6 = 36

36 ÷ 2 = 18

18 ft² + 18 ft² = 36 ft²

100 ft² - 36 ft²

64 ft²

Answer:

Step-by-step explanation:

SO LETS FIND THE AREA OF THE SQUARE ( THE BASE )

8 x 8 = 64

so we have 64

SO LETS FIND THE AREA OF THE TRIANGLE ( THE LATERAL AREA )

area = (1/2) · b · h

(1/2) x 8 x 9

1/2 x 72 = 36

SO THERE ARE FOUR TRIANGLES

36 x 4 = 144

SO 144 + 64 = 208 SO THE ANSWER IS 208 :)

[tex]5\sqrt{2}[/tex] or 7.0710... (7.1)

--Explanation--

If you look closely the triangle on the left could be moved to the space on the right of the shape.

Then, the edges would be 10 inches (top) and 5 inches (sides).

From there, you multiply 10 x 5 to get 50. If you want the square root, you do [tex]\sqrt{50}[/tex] which is how I got 7.071067812, or 7.1, which was rounded to the nearest tenth.

Step-by-step explanation:

10 and 5

There are 8 big fish for every 10 small fish, There are 4 big fish for every 5 small fish.

A proportion is a fraction of a total amount, and the measures are related using a rule of three. The relations between variables, either direct or inverse proportional, can be built to find the desired measures in the problem.

We need to find the number of small fishes for 4 big fish.

We can see that the big fish and small fish numbers are in proportion to each other.

Assume the small fish corresponding to 4 big fish be 'x'.

Therefore, using the proportion of two quantities, we have;

[tex]\dfrac{8}{10}=\dfrac{4}{x}[/tex]

Now on cross multiplying we get:

8x = 4×10

8x =40

Dividing both sides by 8, we get:

x=5

Hence, there are 4 big fish for every 5 small fish.
