Answer:
16w^4
Step-by-step explanation:
(2w)^4 is just 2w mulitplied by itself 4 times. we can do this step by step and multiply the 2 by itself 4 times first:
2 x 2 x 2 x 2 or 2^4 = 16
next we can multiply w by itself 4 times:
w x w x w x w or w^4 = w^4
our answer would be 16w^4
you can also multiply it without breaking it down like this:
2w x 2w x 2w x 2w = 16w^4
Answer:
1kg = 1000g
Then in grams, it's 2000g for the entire bag
therefore
Answer:
10 hours
Step-by-step explanation:
45 pages per 1 hour and 30 minutes, or 60 min +30 min =90 min
90 minutes / 45 pages has to be equal to an equivalent fraction where we have 300 pages
90 minutes /45 pages = ? minutes / 300 pages , multiply both sides by 300
? minutes = 90*300/45 = 600 minutes
to read 300-page book will take 600 minutes = 10 hours
Let x be the whole number. x^2 is the square of the number. x-1 is the preceding number. And x+1 is the following number.
(x+1)(x-1)=
x^2 + x - x - 1
x^2 -1
Your answer is x^2-1 which is one less that x^2. This also means that the square of any whole number (x^2) is one greater than the product of the preceding (x-1) and the following (x+1).
