Answer:

x=11

Step-by-step explanation:

Notice that the first diagram is similar with the second diagram with ratio 1:2

Ex: Side length of JK is 6 and NP being 12, 6:12→1:2

You can conclude that x:22 needs to follow the ratio of 1:2

Thus, x=11

What is the factored form of x^3 -1
lianna [129]

Answer:

The factored form of x^3 -1 will be:

x^3-1^3=\left(x-1\right)\left(x^2+x+1\right)

Step-by-step explanation:

Given the expression

x^3-1

Rewrite 1 as 1³

=x^3-1^3

\mathrm{Apply\:Difference\:of\:Cubes\:Formula:\:}x^3-y^3=\left(x-y\right)\left(x^2+xy+y^2\right)

x^3-1^3=\left(x-1\right)\left(x^2+x+1\right)

            =\left(x-1\right)\left(x^2+x+1\right)

Thus, the factored form of x^3 -1 will be:

x^3-1^3=\left(x-1\right)\left(x^2+x+1\right)

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
