1. 12x^2-8x

2. x^2+5x-36

3. 3x^2+10x+8

Please show all the work for how to solve these problems, thanks.​

Answers

Answer 1

Answer:

Step-by-step explanation:

1) the two members of the expression has 4x in common, so we can rewrite it as: 4x(3x-2)

2) we have to find two numbers that multipied give -36 and that added up give 5

the two number are 9 and -4

we can rewrite the expression as : (x+9)(x-4)

3) we have to solve the associated equation

3x^2+10x+8 = 0

Δ/4 = 25-24 = 1

x1 = (-5+1)/3 = -4/3

x2 = (-5-1)/3 = -2

now we can rewrite the expression as

3(x+4/3)(x+2) = (3x+4)(x+2)

Answer 2

Answer:

1. 12x^2-8x

taking common 4x

4x(x-2)

2. x^2+5x-36

doing middle term factorization

x²+9x-4x-36

x(x+9)-4(x+9)

(x+9)(x-4)

3. 3x^2+10x+8

Doing middle term factorization

3x²+6x+4x+8

3x(x+2)+4(x+2)

(x+2)(3x+4)

What is the prime factorization of 110?

Answers

Answer:

The prime factors of 110 are 2, 5, and 11.

Step-by-step explanation:

First, 110 = 2 * 55

Next, 55 = 5 * 11

Thus, the prime factors of 110 are {2, 5, 11}

Answer:

2 x 5 x 11 = 110.

Step-by-step explanation:

The prime factors of 110 are 2, 5, and 11.

-Factors of 110: 1, 2, 5, 10, 11, 22, 55 and 110

-Prime Factorization of 110: 110 = 2 × 5 × 11

1 × 110 = 110

2 × 55 = 110  

5 × 22 = 110

10 × 11 = 110

11 × 10 = 110

22 × 5 = 110

55 × 2 = 110

110 × 1 = 110

A 30 pack of Flaming Hot Cheetos cost $10.82 at
Costco. A 50 pack of Flaming Hot Cheetos cost
$17.25.

a) Which is the better buy? (You are trying to
compare the cost of a 30 pack and 50 pack of
chips. This is not possible without finding
the unit rate.)

b) What is the difference between the unit
prices? (You need to use the information
from part a to answer this question.)​

Answers

Answer:

50 pack

[tex]\$0.01[/tex]

Step-by-step explanation:

Number of packs at Costco = 30

Cost of 30 packs at Costco = $10.82

Number of packs at the other place = 50

Cost of 50 packs = $17.25

Cost of one pack when 30 packs are bought

[tex]\dfrac{10.82}{30}=\$0.36[/tex]

Cost of one pack when 50 packs are bought

[tex]\dfrac{17.25}{50}=\$0.35[/tex]

It is better to buy the 50 pack.

Difference in the unit prices = [tex]0.36-0.35=\$0.01[/tex].

Basically, you are going to evaluate 5n - 4 from n = 1 to n = 18. Don't forget to add as you evaluate.

I will get you started.

Let n = 1 and then n = 2.

5(1) - 4 + 5(2) - 4 + the rest

5 - 4 + 10 - 4 + the rest

1 + 6 + the rest

7 + the rest

Just continue the pattern. You will then let n be 3, 4, 5, etc all the way to 18.

Find the area of each figure and round to the nearest tenth if necessary

Answers

Given:

The figure of two semicircles with diameters 6 cm and 5 cm.

To find:

The area of the combined figure.

Solution:

It is given that the diameters of the semicircles are 6 cm and 5 cm so their radii are 3 cm and 2.5 cm respectively.

Area of a semicircle is:

[tex]A=\dfrac{1}{2}\pi r^2[/tex]

So, the combined area of two semicircles with radii 3 cm and 2.5 cm is:

[tex]Area=\dfrac{1}{2}\pi (3)^2+\dfrac{1}{2}\pi (2.5)^2[/tex]

[tex]Area=\dfrac{1}{2}\pi (9)+\dfrac{1}{2}\pi (6.25)[/tex]

[tex]Area=14.137167+9.817477[/tex]

[tex]Area=23.954644[/tex]

Round the value to the nearest tenth (one decimal place.

[tex]Area\approx 24.0[/tex]

Therefore, the area of given figure is 24.0 sq. cm.
