Answer with explanation:

Pascal Triangle is Associated with finding the value of nth power of sum or difference of two variables.

The Expression

                (a\pm b)^n, has n+1 , terms.

1-(a+b)^0=1\\\\2-(a+b)^1=a+b\\\\3-(a+b)^2=a^2+2 a b+b^2\\\\4-(a+b)^3=a^3+3a^2b+3ab^2+b^3\\\\5-(a+b)^4=a^4+4a^3b+6a^2b^2+4ab^3+b^4\\\\.......

Now expressing the expression in the form of Pascal's Triangle

                                            1

                                        1                1

                               1              2(1+1)               1

                          1            3(2+1)               3(2+1)            1

                 1            4(3+1)              6 (3+3)             4(3+1)         1

        1         5 (4+1)            10(6+4)            10 (6+4)            5(4+1)       1

1      6(5+1)       15(10+5)      20 (10+10)        15(10+5)        6(5+1)       1

1   7(6+1)   21 (15+6)    35 (20+15)  35(20+15)    21(15+6)  7(6+1)       1

Eight Row is Required to expand the expression →→

      (2x^3+3y^2)^7

mr Goodwill [35]
I don’t know what the answer options are so here I go guessing:

M<4 is the opposite but has the same degree
M<6 is the same as M<2
M<8 is the opposite but has the same degree
Any of these are correct. I’m just not sure what the options were/are.

The swim camp cost $280. How long will it take Kareem to save enough for tbe camp?
aev [14]
I want to help you but your question is missing multiple variables. To answer the question you need to know how much Kareem is making. Whether its a certain amount per task or per day or over a certain amount of time. And it depends on how long she has to save up for camp you know when camp starts and if she has enough time to have enough money saved up. You can message me if you have anymore questions about this. Hope this was helpful.
