Ali's solution is incorrect.

Ali had to add both the terms and should get 10y answer, and not multiply both terms and get answer 9y^2 which is wrong.

Step-by-step explanation:

Ali simplifies the expression 9y+y to 9y2. We need to identify if Ali's solution is correct or incorrect.

Ali's solution is incorrect.

Reason:

We are given the expression: 9y+y

When we add two like terms ( terms having the same variable and exponent), we add the coefficients of both like terms.

In our case 9y+y = 10y

Whereas Ali has done multiplication of both terms and not addition.

In multiplication we add the exponents of the same variables i.e 9y+y = 9y^2

So, Ali had to add both the terms and should get 10y answer, and not multiply both terms and get answer 9y^2 which is wrong.

There are 40 people at Drake's sweet sixteen party. Drake's only rule is that everyone in the party must meet and shake each oth
nikdorinn [45]
1) This is a combination, so use ⁴⁰C₂.
     ⁴⁰C₂ = 780
     There are 780 handshakes in total.

2) I got my solution by using the combinations formula. Or another way you              could do this is to add up... 39 + 38 + 37 + 36 + 35 + 34 + 33 + 32 + 31... +1.          You will end up with 780 (I did this to double check my work).

3) The quickest way to figure this out if Drake invited 1,000 people is to use the       natural numbers formula = n(n+ 1)/2.
     Plug the numbers in: 999(1000)/2 = 499,500 
     If Drake invited 1,000 people, there would be 499,500 handshakes.
