Let's multiply out the equation 6x+2 times 6x+2 using the square. Draw a 2 by 2 bow and put the equation across the bottom and verically. Multiply across to get this. 6x times 6x =36x^2 6x times two =12x do it again and get 12x. 2*2=4. That means x would equal 24.
Answer:
No this is not the same as cos(2Ф)
Step-by-step explanation:
First I changed the 
Ф into 1-
Ф
I then foiled the (1-2Ф)(1-Ф) and that resulted in 1-Ф-2Ф+2
Ф
From there, I then cancelled the two 2Ф and combined like terms and was left with 1-3Ф
Now 1-3Ф ≠ cos(2Ф)
Answer:
100 cm 3
Step-by-step explanation:
20 x 1 = 20
20 x 5 = 100 cm 3
<em>100 cm 3 is the volume</em>
