Three consecutive even integers are such that the square of the third is 76 more than the square of the second. Find the three i

Arada [10]

Let n represent the interger l, the three consective intergers are represented by

$n$

$n + 2$

$n + 4$

The second one represent

$(n + 2) {}^{2} + 76 =( n + 4) {}^{2}$

Simplify both sides

$n {}^{2} + 4n + 4 + 76 = {n}^{2} + 8n + 16$

${n}^{2} + 4n + 4 = {n}^{2} + 8n - 60$

$4n + 4 = 8n - 60$

$4n + 64= 8n$

$64= 4n$

$n = 16$

The intergers are 16,18,20

The 6th term is 22 and the common difference is 6. what is the 50th term

Tom [10]

The general formula for an arithmetic sequence is:
<span>a(n) = a + d(n - 1) </span>

<span>a : first term </span>
<span>d : common difference (6) </span>
<span>n : number of the term </span>

<span>In your example, you are told the 6th term is 22. </span>
<span>a(6) = a + 6(6 - 1) = 22 </span>
<span>a + 30 = 22 </span>
<span>a = 22 - 30 </span>
<span>a = -8 </span>

<span>So now you have the general formula: </span>
<span>a(n) = -8 + 6(n - 1) </span>

<span>If you like you can simplify it: </span>
<span>a(n) = -8 + 6n - 6 </span>
<span>a(n) = 6n - 14 </span>

<span>Then you can plug in n = 50: </span>
<span>a(50) = 6(50) - 14 </span>
<span>= 300 - 14 </span>
<span>= 286</span>

Given and proof with the figure below. <br> Complete the following proof

nevsk [136]

Answer:

2 step proof, Subtraction Property

Step-by-step explanation:

This one is pretty easy if you know a shortcut. Addition, Subtraction, Multiplication, and division properties.

Think about it this way. Subtract angle 1 from QUS. Then subtract angle 2 from RUT. Knowing RUT is equal to QUS means that the differences are the same.

Don't know if this is right or not but hope this helps.

Here's my work
