Equation at the end of step 1 : (((4•(a2))•b)-((8•(a3))•(b5)))+2ab7Equation at the end of step 2 : (((4•(a2))•b)-(23a3•b5))+2ab7 Step 3 :Equation at the end of step 3 : ((22a2 • b) - 23a3b5) + 2ab7 Step 4 :Step 5 :Pulling out like terms :

5.1 Pull out like factors :

 -8a3b5 + 4a2b + 2ab7 = -2ab • (4a2b4 - 2a - b6)

Trying to factor a multi variable polynomial :

5.2 Factoring 4a2b4 - 2a - b6

Try to factor this multi-variable trinomial using trial and error

Factorization fails

Final result : -2ab • (4a2b4 - 2a - b6)

20. The figures are similar. Find x.

Answer:

Step-by-step explanation:

You can see that both triangles are the same except for one thing: one is smaller. Since 7 is half of 14 and both triangles are similar, x stands for 10. That is because 10 is half of 20! :D

Marta is making two different charms for necklace one charm has a 1 cm diameter and a 3.14 cm circumference of a similar charm h

EastWind [94]

From what I can pick up from your problem statement, you want to know "a similar charm has a diameter of 4 cm what is the circumference." Please, would you use proper punctuation in your writing, for greater clarity:

"A similar charm has a diameter of 4 cm. What is the circumference?"

The formula for the circumference of a circle, when the diameter is known, is

C= $\pi$ d or C=pi*d

In this case, with diamter 4 cm, the circumference, C, is 4pi cm.
