A square of area 36cm2 is cut into 2 rectangles A and B. The ratio of area A to B is 2:1. Work out the dimensions of rectangles A and B

first, we need to find side of square

36:3=12cm^2 - for 1 part

first rectangle has area of

12*2=24cm^2

secomd rectandle has area of

12*1=12cm^2

first side of rectangles is 6cm

second side of first rectangle:

second side of second rectangle:

the dimensions of first rectangle: 4 and 6

the dimensions of second rectangle: 2 and 6

3. (5x + 1) - (-10x + 6)

simplify the answer choice. combine like terms. remember to distribute the negative to the terms inside the second parenthesis. also remember that two negatives = one positive, and one of each sign = negative.

- (-10x + 6) = + 10x - 6

simplify. combine like terms:

5x + 1 + 10x - 6

5x + 10x + 1 - 6

15x - 5

∴ it is your answer
