Will give brainleist hurry super easy.
simplify each expression.
1. x + 4x + 6x= 2. 3x + 4x+ 5x = 3. 9(5)= 4.3x+8y+13x= 5.7(3x +5y)= 6. 3x+6x+2x=

The figure above shows the lengths of thesides of a rectangle in cm. find the valuesof x and y and then the area of the rectangle.sides: top= 3x - yleft= 3y + 4bottom= 2x + yright= 2x - 3 use both methods, elimination and substitution, if possible.

If 1 is divided by the sum of y& 4. the result is equal to 3 divided by 4 .find the value of m?

If the ratio of sum of the first m and n terms of an ap is m2 : n2 , show that the ratio of its mth and nth terms is (2m − 1) : (2n − 1).
