Can someone do these two questions for me please. I have a lot of homework to do and I'm trying to get a lot of questions done as possible.

1. is 25

2. I think this one is 25 too?

Step-by-step explanation:

im working on the second

4.) B

8.) I believe it's A

Step-by-step explanation:

4.) go to day 10 and divide 250 by 10 to get 25

8.) its the only one that makes sense

solution:

→c= a b , that is product of a and b is possible only when when a is m × n matrix and b is n × p matrix.

that is, number of columns of a= number of rows of b.

so, size of matrix , c= a b is , if a = (m × n)matrix

b= (n × p)matrix

then a b = [ (m × n)matrix] ×[   (n × p)matrix ]

→→c= a b= [m × p ] matrix

→→size of product a b will be equal to = number of rows of a × number of columns of b

step-by-step explanation:

the true ones are a b and d
