Which row of pascal’s triangle would you use to expand (2x + 10y)15? row 10 row 12 row 15 row 25

Row 15 is correct

Step-by-step explanation:

Pascal's triangle:

                                               1                                            n = 0 , Row = 0

                                       1                 1                                  n = 1  , Row = 1

                              1               2                1                          n = 2 , Row = 2

                                                :

                                           .........

                                            .......

For n = 0, Row number 1

For n = 1,  Row number 2

For n = 2, Row number 3

We make pascal's triangle but sum of above two number, write below.

As we can see in pascal's triangle.

Exponent represent the number of row.

If binomial has exponent n then nth row of pascal's triangle use.

For

Here power is 15

So, we have to use 15 row of pascal's triangle.

Hence, Row 15 is correct

area = length x width

length = 2 x width

32 = 2 x width x width

32 = 2 x width^2

36 = width ^2  

width = 6

length = 12

area is 32

perimeter = 2 x 12 + 2 x 6 = 24 + 12 = 36

step-by-step explanation:

just do 5.2 + 2 ( 7.2) and 1/3 x 3 (.9) and youv'e got your equation. 0.9( 9/10) + 7.2 ^2 = 16.4 hope i could !
