Hello,
1) k = (-5) * (-5) = 25
3) x = 12 * 0 = 0
5) y = (-4) * (-12) = 48
7) z = 0 * 9 / 1 = 0
9) x= 18 / -3 = -6
11) p = -8 / 8 = -1
13) h = 42 / 14 = 3
15) m = -42 / 6 = -7
17) x = -9 * -11 = 99
19) v = -17 / -17 = 1
21) h = 3,136 / 56 = 0,056
23) x = 4,200 / 30 = 0,14
25) m = 21 * -3 = -63
Bye :)
The <em>correct answer</em> is:
400 + 10 + 2 + 0.6 + 0.03 + 0.008.
Explanation:
To write a number in expanded form, we use place values.
4 is in the hundreds place; this makes its value 400.
1 is in the tens place; this makes its value 10.
2 is in the ones place; this makes its value 2.
6 is in the tenths place; this makes its value 0.6.
3 is in the hundredths place; this makes its value 0.03.
8 is in the thousandths place; this makes its value 0.008.
To write this together, we find the sum:
400 + 10 + 2 + 0.6 + 0.03 + 0.008.
So prime factorization is as it seems, finding the prime factors for a number. With this number, break it down as such:
