Oh, dude, you're hitting me with some math now? Okay, so when you multiply 2w by 7w, you basically just multiply the numbers (2 and 7) and then multiply the variables (w and w). So, 2 times 7 is 14, and w times w is w^2. Put it all together, and you get 14w^2. Easy peasy lemon squeezy.

What is the simplest form of the expression w plus 2x plus 3w - 2xw?
w + 2x + 3w - 2xw = 2x + 4w - 2xw, in simplest form
How do you slove the polynomial 25y2-49w2?
25y2 - 49w2 = (5y)2 - (7w)2 = (5y - 7w)(5y + 7w)
How do you solve this trinomial 56w2 plus 17w-3?
56w2 + 17w - 3 = 56w2 + 24w - 7w - 3 = 8w(7w + 3) - 1(7w + 3) = (7w + 3)(8w - 1)
What is -2 over 7w equals 8?
Let's start with making the variables coefficient a positive number. This obtained by simply multiply the negative fraction by -1/1, which results in the same fraction just positive. However, what you do to one side you must always do to the other. -2/7w = 8 -1/1 x -2/7w = 8 x -1/1 = 2/7w = -8 Now we see that our variable is still attached to the coefficient by means of multiplication. We must perform the inverse operation to detach the variable. In our case, division will suffice. 2/7w ÷ 2/7 = -8 ÷ 2/7 1/w = -8 ÷ 2/7 1/w = -28 w = -1/28. Is it (-2 over 7)w or -2 over (7w)?
What is the answer to solving for w 7w equals -217?
