Whats the answer to 8p squared minus 16 p=10

goblinko [34]

8p² - 16p = 10

8p² - 16p - 10 = 0 Divide through by 2

4p² - 8p - 5 = 0

Multiply first and last coefficients: 4*-5 = -20

We look for two numbers that multiply to give -20, and add to give -8

Those two numbers are 2 and -10.

Check: 2*-10 = -20 2 + -10 = -8

We replace the middle term of -8p in the quadratic expression with 2p -10p

4p² - 8p - 5 = 0

4p² + 2p - 10p - 5 = 0

2p(2p + 1) - 5(2p + 1) = 0

(2p + 1)(2p - 5) = 0

2p + 1 = 0 or 2p + 5 = 0

2p = 0 -1 2p = 0 - 5

2p = -1 2p = -5

p = -1/2 p = -5/2

The solutions are p = -1/2 or -5/2

Faucet A flows at a rate of 100 liters per 5 minutes and Faucet B flows at a rate of 100 liters per 4 minutes into an empty pool

Dmitriy789 [7]

Answer:

It will take both faucets 200 minutes to fill a pool with 9,000 liters of water

Step-by-step explanation:

Here, we want to know the time it will take for both faucets to fill a pool with 9,000 liters of water

What we need here is to have a joint rate for both faucets;

For the first faucet, we have a rate of 100 liters per 5 minutes so this means in a minute;

100/5 = 20 liters per minute

For the second faucet, the per minute rate will be 100/4 = 25 liters per minute

So therefore, the joint rate will be;

25 liters per minute + 20 liters per minute = 45 liters per minute

So the time needed to fill 9,000 liters of water in a pool will be ;

9000 liters/ 45 liters per minute = 200 minutes
