4. If APQR is congruent to ASTU as shown in the given figure, then what is the length of TU?
5 cm
5 cm
R
6 cm
(a) 5 cm
(c) 7 cm
S
(b) 6 cm
(d) Cannot be determined

the answer

b. they are parallel and will never intersect.

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

the correct answer is you spend $55.78 more in a brand store that buy ing in a normal store.

step-by-step explanation:

brand = spend   $ 135.85 total

store = spend $80.07 total
