Answer:
<h3>5</h3>
Step-by-step explanation:
Given the expression
2a^3−10ab^2+3a^3−ab^2−7
We are to find the coefficient of a^3
First is to collect the like terms;
2a^3−10ab^2+3a^3−ab^2−7
= 2a^3+3a^3−10ab^2−ab^2−7
= 5a^3-11ab^2-7
From the resulting equation, you can see that the coefficient of the term having a^3 is 5
-6 and -6 multiply to get 36 but add to get -12.
Hope this helps!
Answer:
(0,0),(-4,6),(4,-6)
Step-by-step explanation:
Desmos is a helpful site for u to use for a graphing calculator. just type the expression in :)
If, a > b . Then, opposite of a < opposite of b
Example 1 : 3>2 implies -3<-2
Example 2: -2>-3 implies 2<3
Example : 3> -2 implies -3<2
Assuming that your own ticket is already secured.
From the 5 friends you can only choose 3.
The order in which these friends are chosen is not relevant. So this is a Combination problem.
Where the order is relevant the problem becomes a Permutation problem!
So the answer is 5 combination 3. = ⁵C₃
⁵C₃ = (5 * 4 * 3) / ( 3 * 2 * 1) = 10
You can take 10 groups of any 3 of your 5 friends.
