Answer:different of two squares states that

If a²-b² is given then

a²-b²=(a+b)(a-b)

Now to answer the question

(x+2)²-(x)²=68

(x+2+x)((x+2)-x)=68

(2x+2)(x+2-x)=68

(2x+2)(2)=68

Divide both sides by 2

{(2x+2)(2)}÷ 2 = 68/2

2x+2= 34

Collect like terms

2x=34-2

2x=32

Divide both sides by 2

2x/2 =32/2

x=16

Hence

x=16

x+2=16+2=18

The two consecutive even integer are 16 and 18

Solve the system of equations below by graphing both equations with a pencil and paper. What is the solution? y = x+1 1 X+ 3 2.
Troyanec [42]

Answer:

D. (4, 5)

General Formulas and Concepts:

<u>Pre-Algebra</u>

  • Order of Operations: BPEMDAS
  • Equality Properties

<u>Algebra I</u>

  • Solving systems of equations using substitution/elimination
  • Solving systems of equations by graphing

Step-by-step explanation:

<u>Step 1: Define systems</u>

y = x + 1

y = 1/2x + 3

<u>Step 2: Solve for</u><u><em> x</em></u>

  1. Substitute in <em>y</em>:                              x + 1 = 1/2x + 3
  2. Subtract 1/2x on both sides:        1/2x + 1 = 3
  3. Subtract 1 on both sides:              1/2x = 2
  4. Divide both sides by 1/2:              x = 4

<u>Step 3: Solve for </u><em><u>y</u></em>

  1. Define original equation:                   y = x + 1
  2. Substitute in <em>x</em>:                                    y = 4 + 1
  3. Add:                                                     y = 5

<u>Step 4: Graph</u>

<em>We can confirm our answer.</em>

Find the 44th percentile, P44, from the following data! pls help
irina [24]

Answer:

P_{44} = 29.9

Step-by-step Explanation:

The 44th percentile, P_{44}, of the given data can be calculated using the kth formula for percentile given as:

i = \frac{k}{100}(n + 1)

where,

i = the ranking or the position of the percentile = ?

k = the percentile = 44

n = total number of the given data values = 23

Plug in the values into the formula to find "i"

i = \frac{44}{100}(23 + 1)

i = \frac{44}{100}(24)

i = \frac{1,056}{100}

i = 10.56

Since "I", 10.56, is not an integer, round the number down, and round it up to the nearest integer, then look for the position each occupy in the ordered data set, and find their average.

Thus,

i_{down} = 10.56 = 10

i_{up} = 10.56 = 11

The data occupying the 10th position on the data set = 28.7

11th = 31.1

P_{44} = \frac{28.7 + 31.1}{2} = \frac{59.8}{2}

P_{44} = 29.9

What is the correct simplified form of 3±95√3 ?
sergejj [24]

Answer:

3±95√3  is simplified as  167.5495  or  - 161.5495

Step-by-step explanation:

Given expression;

3±95√3

This expression can be simplified as;

3±95√3 = 3 + 95√3             or     3 - 95√3

              = 3 + 95(1.7321)      or   3 - 95(1.7321)

              = 3 + 164.5495       or    3 -  164.5495

              = 167.5495             or     - 161.5495

Therefore, 3±95√3  is simplified as  167.5495  or  - 161.5495
