The answer is B) $18.00. (21.25)(.85) = $18.0625, and the closest is $18.00
1 because 3 points determine a plane.
To convert 8.0464x10^-7 from scientific notation to decimal notation, you need to move the decimal point to the left seven times.
Therefore the answer is:
0.00000080464
Note: 10^-7 equals 1/10^7
8.0464x10^-7 can be rewritten as:
8.0464/10^7 (i.e. divide 8.0464 by 10000000)
which results: 0.00000080464
You can remove the parentheses:-
= 7q^3r^2 + 5qr^2 + 23q + −5qr^2 − qr^2 − 11q − 4q^3r^2 ( because there is + outside)
Bring like terms together
= 7q^3r^2 − 4q^3r^2 + 5qr^2 − 5qr^2 − qr^2 + 23q − 11q
= 3q^3r^2 - qr^2 + 12q answer
