Your current CD matures in a few days. You would like to find an investment with a higher rate of return than the CD. Stocks historically have a rate of return between 10% and 12%, but you do not like the risk involved. You have been looking at bond listings in the newspaper. A friend wants you to look at the following corporate bonds as a possible investment. a.100 2/6
b.100 3/4
c.100 1/4
d.100 1/3

6xy + 21x + 28y - 4

Step-by-step explanation:

Step 1: Evaluate the length.

4 - 7(3x + 4y)

4 - 21x - 28y

Step 2: Evaluate the width.

3x(-2y)

- 6xy

Step 3: Length + Length and Width + Width

(4 - 21x - 28y) + (4 - 21x - 28y) and (- 6xy) + (- 6xy)

Step 4: Group like terms.

(4 + 4) + (- 21x - 21x) + (- 28y - 28y) and (- 6xy) + (- 6xy)

8 - 42x - 56y and - 12xy

Step 5: Add them all together.

8 - 42x - 56y - 12xy

Step 6: Order the terms.

- 12xy - 42x - 56y + 8

Step 7: Simplify it.

Final 6xy + 21x + 28y - 4
