You cannot add row 2 to column 3 because they have different dimensions. You can do any of the other operations, but the only one that makes any sort of sense is ...
  Multiply row 2 by -1 and add it to row 3

_____
It makes no sense to multiply a row by zero. That makes the entire row zero and makes the matrix useless for finding any sort of solution.

You can switch columns, but that doesn't get you any closer to a solution here.

If I were trying to find a solution, I might
  switch rows 1 and 2
  multiply the new row 1 by -3 and add it to the new row 2
  multiply the new row 1 by 2 and add it to row 3
This sequence of operations will make the first column [1 0 0], reducing the problem to 2×2 from 3×3.

A rectangle has a length of 5.50 m and a width of 12.0 m. What are the perimeter and area of this rectangle?
natulia [17]
Perimeter is all the sides added together so 5.50 + 12 + 5.50 + 12 = 35 and area is base times height so 5.5 × 12 = 66

P = 35m
A = 66m

A campground says campers can rend a square space taking up 225 square feet. How long would one side of the space be?
Helga [31]

Answer:

56.25 ft

It is simple, since it is a square the sides are all the same length so you take A=area and divide it by four= h or w or l (height, width, length) so

225/4=56.25
