How do i express this as a trinomial
(2x+5)(3x+7)

6x^2 + 29x + 35

Step-by-step explanation:

(2x+5)(3x+7)

multiply 2x with 3x and 7

multiply 5 with 3x and 7

simplify

6x^2 + 14x + 15x + 35

= 6x^2 + 29x + 35

3: 2

step-by-step explanation:

shorter piece is 2: 3, so just reverse it, and you get 3: 2

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
