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

the answer is d. 75%

5x + 5

step-by-step explanation:

you should always add the diagrams and graphs we cannot see. this particular question is kind of borderline because we can make a graph for you.

(f + g)x = -x^2 +3x + 5 + x^2 + 2x

(f + g)x = 5x + 5

the graph of z = 5x + 5 is shown below. always use desmos when in doubt.
