Im Trying To Do This Equation But Dont Know Where The 2 Came From When You Square It. Can Somebody Explain

Answers

Answer 1
okay so at the bottom it says square both sides so you have to square (x+1). when you do that you're basically just doing (x+1)(x+1) and you just use the foil method and end up with x^2 + 2x + 1

Sean is trying to find the area of a square,
• The side length of the square is equivalent to the side length of an equilateral triangle,
The perimeter of the equilateral triangle is 24x + 18.
Find the expression that models the area of the square

Answers

An equilateral Triangle has 3 equal sides.

Divide the perimeter by 3 to get the length of one side.

24x + 18 / 3 = 8x + 6

The area of a square is S^2

Area = (8x+6)^2

Apply the perfect square formula to get:

64x^2 + 96x + 36

A television broadcasting company wants to broadcast every game of a large
tournament. The first round of the tournament has 64 games, and each
subsequent round has half as many games as the previous round.
How many total games will the broadcasting company need to broadcast in the
first 5 rounds of the tournament?

Answers

Answer:

124

Step-by-step explanation:

64 • 1/2= 32

32•1/2=16

16•1/2=8

8•1/2=4

64+32+16+8+4

Your answer would be 124, hopefully I could help!

A man sells 8 articles for Rs. 7360 and makes a profit of
15%. Find the gain or loss percent if he sells 13 such
articles for Rs. 11440.
(Ans: 10% gain)​

Answers

Answer:

SP of 8 articles =Rs 7360

Profit=15%

Now,

SP of each article =7360/8= Rs920

Wkt,

SP=CP+profit (let CP=x)

920=x+15%of CP

920=x+15÷100× x

920=x+15x÷100

920=(100x+15x)÷100

920=115x÷100

92000=115x

92000÷115=x

Therefore, x=Rs 800

CP=800(i.e Cost price of one article)

Again,

SP of 13 articles=Rs 11440

SP of 1 article=11440÷13=Rs 880

Since,SP>CP

Profit!

Profit=SP-CP

=880-800

=Rs 80

Profit%=profit÷CP×100%

=80÷800×100

=10%

A stick l feet long broken into two parts, one of which is twice as long as the other. How long is the shorter piece? Use algebra

Answers

Answer:

the shorter piece is L ÷ 3 feet long in the case when the original stick is L feet long

Step-by-step explanation:

It is given that

The stick is L feet long

And, the two pieces are x and y

Now according to the question

It is given that

one of which is twice as long as the other

so,  

x = 2y

x + y = L

Put the value of x in the above equation

So,  

2y + y = L

3y = L

Now divide by 3

y = L ÷ 3

Hence, the shorter piece is L ÷ 3 feet long in the case when the original stick is L feet long

Answer:

l/3

Step-by-step explanation:

its not one third the answeris the variable L divided by 3

Suppose f(x)=x^2 what is the graph of g(x)=f(2x)

Answers

Answer:  

The graph is attached.  

Step-by-step explanation:

Since g(x) = f(2x), this means we substitute 2x in place of x for f(x):

g(x) = f(2x) = (2x)² = 4x²

Graphing this, the parabola is not moved from the parent graph f(x) = x², but the graph is compressed horizontally by a factor of 4.
