Answer:

6

Step-by-step explanation:

  1. If you multiply a number from the big polygon by 2/3s, you will get the corresponding number on the small polygon. For example, 6 × 2/3 = 4
  2. To find x, find the corresponding number on the big polygon and multiply it by 2/3s. The number on the big polygon is 9. 9 × 2/3 = 6

I hope this helps!

How do you factor and solve x^2-6x=-5
ArbitrLikvidat [17]

Answer:

Step-by-step explanation:

You need to bring the -5 to the left side.

x^2-6x+5=0

Wat two numbers, when multiplied equal to +5? Also when added make the middle term or -6?  -5 and -1.

(x-1)(x-5)  The x^2 would factor to be x*x

So the answer is the (x-1)(x-5)

In a random sample of fivefive microwave​ ovens, the mean repair cost was ​$75.0075.00 and the standard deviation was ​$13.0013.
Radda [10]
<h2>Answer with explanation:</h2>

As per given , we have

Sample size : n= 5

Degree pf freedom = : df= 5-1=4

\mu=\$75.00

\sigma=\$13.00

Significance level for 90% confidence = \alpha=1-0.90=0.1

Using t-value table , t-critical value for 90% confidence:

t_{\alpha/2, df}=t_{0.05, 4}=2.132.

Margin of error of \mu: E=t_{\alpha/2}\dfrac{\sigma}{\sqrt{n}}\\\\(2.132)\dfrac{13}{\sqrt{5}}=12.3949720129\approx12.39

Interpretation : The repair cost will be within $12.39 of the real population mean value \mu 90% of the time.

What is 8b2 - 8 factored?
erma4kov [3.2K]

Answer:

8 • (b + 1) • (b - 1)

Step-by-step explanation:

Reformatting the input :

Changes made to your input should not affect the solution:

(1): "b2"   was replaced by   "b^2".

Step by step solution :

Step  1  :

Equation at the end of step  1  :

 23b2 -  8

Step  2  :

Step  3  :

Pulling out like terms :

3.1     Pull out like factors :

  8b2 - 8  =   8 • (b2 - 1)

Trying to factor as a Difference of Squares :

3.2      Factoring:  b2 - 1

Theory : A difference of two perfect squares,  A2 - B2  can be factored into  (A+B) • (A-B)

Proof :  (A+B) • (A-B) =

        A2 - AB + BA - B2 =

        A2 - AB + AB - B2 =

        A2 - B2

Note :  AB = BA is the commutative property of multiplication.

Note :  - AB + AB equals zero and is therefore eliminated from the expression.

Check : 1 is the square of 1

Check :  b2  is the square of  b1

Factorization is :       (b + 1)  •  (b - 1)

Final result :

 8 • (b + 1) • (b - 1)
