Using a meter stick, I measured the width of the classroom to the nearest cm. The classroom is 11 meter sticks long plus 49 cm on the 12th meter stick. How wide is the classroom in m? how wide is it in cm? how are the two numbers different?

Talia grouped the terms and factored out the gcf of the groups of the polynomial 15x2 – 3x – 20x + 4. her work is shown below. (15x2 – 3x) + (–20x + 4) 3x(5x – 1) + 4(–5x + 1) talia noticed that she does not have a common factor. what should she do?
