What is the product of (2p + 7)(3p2 + 4p – 3)?
Nitella [24]
The answer is <span>C=6p3 + 29p2 + 22p – 21</span>

To calculate the product, we need to multiply each member of each multiplier:
(2p + 7)(3p2 + 4p – 3) = 2p · 3p² + 2p · 4p + 2p · -3 + 7 ·3p² + 7 · 4p + 7 · -3
                                    =    6p³     +     8p²    -     6p    + 21p²   +  28p   -     21
                                    = 6p³ + 8p² + 21p² + <span>28p - 6p -21
                                    = </span>6p³ + 29p² + 22p - 21

Therefore, the product of (2p + 7)(3p2 + 4p – 3) is 6p³ + 29p² + 22p -21

Not sure I would solve this problem or where to start? Can someone help me out here please?
Kaylis [27]

Answer:

$2419469.58

Step-by-step explanation:

You are given the original player salary and told that there is a pay decrease of 2.7%.

So New Salary= Original Salary-Pay Decrease.

If original is 100% and pay decrease is 2.7% then the new salary is 97.3% of original.

New Salary= 0.973*2486609=$2419469.58
