9514 1404 393

Answer:

  9c² -4p²

Step-by-step explanation:

The product of a sum and difference of the same two terms is the difference of their squares:

  (3c +2p)(3c -2p) = 3c(3c -2p) +2p(3c -2p)

  = (3c)² -6cp +6cp -(2p)²

  = (3c)² -(2p)² = 9c² -4p²

There are 4 consecutive odd integers that sum to 120.
allsm [11]

Answer:

27, 29, 31, 33

Step-by-step explanation:

Let x represent the smallest odd integer then...

x+2 represents the second

x+4 represents the third

x+6 represents the fourth

We can use this to set up an equation:

x+x+2+x+4+x+6=120

Combine like terms

4x+12=120

Subtract 12 from both sides

4x=108

Divide both sides by 2

x=27

The integers are 27, 29, 31, 33
