# Project #25992 - Reduction

Find the sum of:

• + 7y and y + 6x

Find the difference between:

• 18x + 18y and 3x - 15y

Reduce these:

• x(x+ 3y) + y(y + 6x) + 12x
• b x -(5x + 2y) + (3x - y) + (17y + 10x)
• c 24x + (12x - 4y) - (10x - 15y)

Reduce these:

• a 5(2x - 5y) + 3(4x + 6y)
• b 6(2x - 4y) - 4(3x - 6y)

Put the biggest possible factor in front of the bracket

• a 12xy + 4x + 8
• b 3x² + 9x
• c 5y² + 25y + 15xy

Reduce first the following expression. After that find the value of the reduced expression when x = 4 og y = 1:

5x - (3x - 7y) - (3y + 4x) - (6x + y) +

A. Put a literal expression for the perimeter of the figure

B.  Put a literal expression for the total area of the figure

C. Calculate the perimeter and the area, when a = 30 cm og b = 5 cm.
