Tonya has a small picture with a length 4 1/5 of inches. she wants to enlarge the picture by a factor of 7 and frame it. which of the following is true?

a.
the enlarged picture has a length of inches.

b.
the enlarged picture has a length of inches.

c.
the enlarged picture has a length of inches.

plz solve soon i only have one min left to answer

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

answer: 42

use a calculator to find that 845/73 = 11.575

the whole part of the answer is 11. multiply this by 73 to get 11*73 = 803.

subtract that result from 845 to get 845 - 803 = 42

10 you would take 50/ .2
