  (d)  -2(x +5)

Step-by-step explanation:

For an infinite number of solutions, the left and right sides of the equal sign must have equivalent expressions.

Left side

  -5(x +2) +3x

  = -5x -10 +3x

  = -2x -10

  = -2(x +5)

Right Side Choices

(a) -5x +15 +2x = -3x +15

(b) -5x -10

(c) x -2x +2 +3x = 2x +2

(d) -2(x +5) = -2x -10 . . . . . . . matches left-side expression

step-by-step explanation:

i think you should think about the question and not look online.

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
