(13) The third side is 16.1 cm

Step-by-step explanation:

Given

(13) & (14)

Required

Solve

(13): Let length AB = x.

Using Pythagoras theorem.

[tex]x^2 = 12^2 + 9^2[/tex]

[tex]x^2 = 144 + 81[/tex]

[tex]x^2 = 225[/tex]

Take positive square root of both sides

[tex]x = \sqrt{225[/tex]

[tex]x = 15[/tex]

(14): Let length DE = x.

Using Pythagoras theorem.

[tex]x^2 = 8^2 + 14^2[/tex]

[tex]x^2 = 64 + 196[/tex]

[tex]x^2 = 260[/tex]

Take positive square root of both sides

[tex]x = \sqrt{260[/tex]

[tex]x = 16.1[/tex] ---approximated

Step-by-step explanation:

first method

add 5 from both side

2x -5 +5 = 7+5

2x= 12

X = 2

12

divide 2 from both side

2. 12

2. 2

X = 6

second method

2x-5=7

2x = 5+7

2x=12

X=2/12

X =6

Step-by-step explanation:

If 6x-4 is 11 less than 25, what is the value of 9x can be rewritten as:

6x-4=25-11, what is the value of 9x?

Let's solve for x first by using the given information: 6x-4=25-11

1. 6x-4=25-11

2. 6x-4=14

3. (isolate x by adding 4 on both sides) 6x=18

4. x=3

The question asks for the value of 9x. Since we know x=3...

9x=9 times 3=27

9x=27

The lengths of sides of the parallelogram are 71 inches and 51 inches. Hence, option (C) is correct.

A unique variety of quadrilateral called parallelogram, a parallelogram has both pairs of its opposite sides parallel and equal.

Let sides of the parallelogram are a and b.

The perimeter of parallelogram  = 2(a+b)

Given that,

The perimeter of parallelogram = 244

implies that,

2(a+b) = 244

a+b = 122       (1)

Also, the difference of sides is 20 inches,

implies that,

a-b = 20       (2)

By solving equation (1) and (2),

a = 71 inches,

b = 51 inches.

The lengths of sides of the parallelogram are 71 inches and 51 inches.

Answer:

[tex]\frac{x^2+2x}{x-3}[/tex]

Step-by-step explanation:

We need to factor out numerator and denominator in order to simplify the rational expression by cancelling  common factors.

Numerator :  x^3 - 4 x = x (x^2 - 4) = x (x - 2) (x + 2)

Denominator (factoring by grouping):

x^2 - 5 x + 6 = x^2 - 3 x - 2 x + 6 = x (x - 3) - 2 (x - 3) = (x - 3) (x - 2)

Then we can cancel out the common factor (x - 2) in both numerator and denominator, leading to:

x (x + 2) / (x - 3) = (x^2 + 2)/ (x-3)

Answer:

B family size

Step-by-step explanation:

The lender will not consider family size when reviewing your loan application.

Loan applications could be declined for so many reasons. However, in a situation where an application is not granted, it is good to find out the reasons behind the decision so as to avoid repeating such in subsequent applications.

Another step to be taken after the denial of the application is to look for an alternative lender and make another application.

One may also need to improve on the application to avoid another denial this time around.

Since Lenders have different risk appetites and preferences. What one lender tells about your creditworthiness is not necessarily what another will. They may view your finances as well enough to apply.

Answer vary:

The better buy is 5 cans of green beans at the Village Market.

Step-by-step explanation:

honestly in my opinion that‘s my answer.

if 10 cans cost $5.10 and 5 cans cost $2.30, think about if you add another $2.30 for another 5 cans the cost is $4.60 and you get 10 cans. and that’s obviously cheaper than the other buy.

10 cans = $5.10

5 cans = $2.30.    

(the 5 can offer)

2.30+2.30= $4.60

Using proportions, it is found that it will take 55.6 hours to fill the poll.

A proportion is a fraction of total amount, and the measures are related using a rule of three.

In this problem, in one hour, 630 gallons of water are delivered. How many hours are going to take to deliver 3.5 x 10⁴ gallons = 35000 gallons?

The rule of three is:

1 hour - 630 gallons

x hours - 35000 gallons

Applying cross multiplication:

[tex]630x = 35000[/tex]

[tex]x = \frac{35000}{630}[/tex]

[tex]x = 55.5[/tex]

It will take 55.6 hours to fill the poll.
