Use the model to show to help find the sum 0.34 plus 0.49

Answer/Step-by-step explanation:

The idea to use in solving this problem using the model, is to express the number of shaded boxes in fraction form.

Thus, the blue red shaded boxes has 34 boxes shaded out of 100 boxes. This represents . This will give us 0.34.

The other shaded boxes represents .

Using the model, we can solve 0.34 + 0.49.

Add both fractions together.

2 x^2 -3x+p

sum of roots = 3/2

let other root be x

3+ x = 3/2

x= 3/2 - 3 = -3/2

product of roots = p/2

3× -3/2 = p/2

-9 = p
