Answer: 14s^4 - 7s^2 + 15</h3>
====================================================
Work Shown:
(12s^4-6s^2+4s)+(6s^4-4s+27)-(4s^4+s^2+12)
12s^4-6s^2+4s+6s^4-4s+27-4s^4-s^2-12
(12s^4+6s^4-4s^4)+(-6s^2-s^2)+(4s-4s)+(27-12)
14s^4-7s^2+0s+15
14s^4-7s^2+15
Note: don't forget to distribute the negative to every term in the last parenthesis
Answer:
6,700,000,000
Step-by-step explanation:
Standard Notation is the normal way of writing numbers.
Scientific notation of 6.7 * 10^9 would mean we need to move the decimal point "9" units "to the right" and arrive at our normal standard form of the number.
So, we move 1 decimal place and create 67. Then with the next 8 moves (to the right), we add 8 more zeros, so the number actually becomes:
6,700,000,000
This is 6 billion, 700 million.
This is the normal standard way (standard notation) of writing numbers.
Answer:
48
Step-by-step explanation:
1/4 x = 12
x = 4*12
x=48
C=2161

One of the equations for a circle is (x - h)² + (y - k)² = r² where (h, k) are the center and r is the radius.
So after substitution:
(x + 6)² + (y - 2)² = 100
Notice the equation has the opposite of h and k and 100 is the result of squaring 10.
