Answer:
6p^3−7p^2+11p−6
Step-by-step explanation:
1. You would want to foil it, which means multiplying one number from each parentheses to the next parentheses, like so:
3p * 2p ^ 2 = 6p^3
3p * -p = -3p
3p * 3 = 9p
-2 * 2p^2 = -4p^2
-2 * -p = 2p
-2 * 3 = - 6
2. Now add all of the numbers we foiled together, thus getting you:
6p^3−7p^2+11p−6
To solve this, you need to have a common denominator for both terms. In order to get the equivalent fraction with the common denominator, you multiply each fraction by a version of 1. Here, it seems like our least common denominator (or LCD) is 12. Therefore, you multiply 1/4 by 3/3 and you multipy 2/3 by 4/4 to get 3/12 plus 8/12 = 11/12.
Hope this helps!

Answer:
B. 4
Step-by-step explanation:
cos(45°) = x/4√2
√2/2 = x/4√2
x = 4√2•√2/2
x = 4
