Multiply (3c+2p)(3c-2p) what is the answer?​
Len [333]

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

svlad2 [7]

Answer:

£13.5.

Step-by-step explanation:

Let the share of Brendon, Asha and Julie is 3x, 2x and 6x respectively.

The total amount of money that Asha and Julie recieve is £36

i.e.

2x+6x = 36

8x = 36

x = (36/8)

Amount recieved by Brendon,

B=3\times \dfrac{36}{8}\\\\=\$13.5

So, the amount of money that brendon receives is £13.5.

A 185-pound person burns 260 calories during a soccer game. Find the number of calories that a 250-pound person would burn durin
Olin [163]

Answer: The answer to this problem is 178 calories.

Step-by-step explanation:

To calculate the answer, simply get the percentage of calories a person would burn during exercise (I am using a calculator BTW).

185 / 260 = 0.711538462

Then, calculate 71.1538462% of 250 pounds.

250 * 0.711538462 = 177.884616

Finally, round up your answer. 177.884616 rounded up is 178.
