No but there's a website where you can calculate what grade you need in order to get a certain grade in the class. Just add the extra credit grade to the grade you have first.
Also, it's extra credit. Why wouldn't you do it? It's FREE points (sort of).
Just copy+paste this URL into your search bar:

Answer:
-9
Step-by-step explanation:
use an equation to solve this
consecutive means in succession, one after the other
since they're odd, both numbers have to be odd
let x be the first number
x+x+2=-20
+2 because if you only +1, one of the numbers would be even
2x+2=-20
-2. -2
2x=-22
x=-11
the smaller would be -9 since we are adding x and x+2 together
Answer:
22
Step-by-step explanation:
QS =2×11 = 22
__________
n = {2, 5, 0} holds true for 2n - 3 < 9
<em><u>Solution:</u></em>
Replacement set is the set of values that may be substituted for the variable.
Plug in each value from the replacement set and evaluate both sides of the inequality
If the inequality is true for a certain value, that value belongs in the solution set.
<em><u>Given equation is:</u></em>
2n - 3 < 9
<em><u>Substitute n = 2</u></em>
2(2) - 3 < 9
4 - 3 < 9
1 < 9
1 is less than 9 is true
Thus n = 2 is a solution to equation
<em><u>Substitute n = 5</u></em>
2(5) - 3 < 9
10 - 3 < 9
7 < 9
7 is less than 9 is true
Thus n = 5 is a solution to equation
<em><u>Substitute n = 0</u></em>
2(0) - 3 < 9
0 - 3 < 9
-3 < 9
-3 is less than 9 is true
Thus n = -3 is a solution to equation
5. Volume of sphere = 4/3 x pi xr ^3
Volume = 4/3 x 3.14 x 2^3 = 33.49 cubic feet.
6 . Volume of cylinder = pi x r^2 x height
Volume = 3.14 x 2^2 x 3 = 37.68 cubic meters
