Answer:

The answer to your question is Area = 49n² - 70n + 25    

Step-by-step explanation:

Data

Length of the side = 7n - 5

Formula

Area of a square = side x side

Process

1.- Substitute values

Area = (7n - 5)(7n - 5)

2.- Expand

Area = 49n² - 35n - 35n + 25

3.- Simplify

Area = 49n² - 70n + 25    

4.- The polynomial is 49n² - 70n + 25

The area of a square is side times side:

So the area of this square is (7n - 5) x (7n-5) or (7n-5)^{2}

Apply FOIL to solve this:

(7n-5) (7n - 5)  

(7n ⋅ 7n) = 49n^{2}

(7n ⋅ -5) = -35n

(-5 ⋅ 7n) = -35n

(-5 ⋅ -5) = 25

Area of square: 49n^{2} -35n -35n + 25

                          = 49n^{2} -70n + 25

three sets of the sum of a number and four are added to the sum of seven times the same number and thirteen
almond37 [142]

The algebraic expression for given statement is: 10x + 25 or 3(x + 4) + (7x + 13)

<em><u>Solution:</u></em>

Given the statement:

Three sets of a sum of a number and four are added to the sum of seven times the same number and thirteen

Let us first understand the given statement,

Let the number be "x"

" sum of a number and four" means x + 4

"Three sets of a sum of a number and four" translated to 3(x + 4)

"sum of seven times the same number and thirteen" means 7x + 13

<em><u>Thus the algebraic expression for given statement is:</u></em>

3(x+4)+(7x + 13)

<em><u>Using distributive property in above expression</u></em>

a(b+c) = ab + bc

Therefore,

3(x+4)+(7x + 13) = 3x + 12 + 7x + 13

<em><u>Combine the like terms</u></em>

3(x+4)+(7x + 13) = 10x+25

Thus the required expression for given statement is: 10x + 25 or 3(x + 4) + (7x + 13)

Hello,

Let's assume i the number of lines,
 u(i) the number of regions:

u_0=1\\\\&#10;u_1=2=1+1=1+u_0\\\\&#10;u_2=4=2+u_1\\\\&#10;u_3=7=3+u_2\\\\&#10;u_4=11=4+u_3\\\\&#10;u_5=16=5+u_4\\\\&#10;...\\\\&#10;\boxed{u_{n+1}=(n+1)+u_{n}}\\\\&#10;&#10;u_{n+1}=(n+1)+n+(n-1)+...+1+u_0\\\\&#10;&#10;\boxed{u_{n+1}= \dfrac{(n+1)*(n+2)}{2}+1 }
