Rewrite it in the form a^2 + 2ab + b^2, where a = y^2 and b = 6

(y^2)^2 + 2(y^2)(6) + 6^2

Use the Square of Sum: (a + b)^2 = a^2 + 2ab + b^2

<u>(y^2 + 6)^2</u>

Find the product of (2x − 5y)2
pishuonlain [190]

Answer:

(2x - 5y)²

(2x - 5y)(2x - 5y)

2x(2x - 5y) - 5y(2x - 5y)

2x(2x) - 2x(5y) - 5y(2x) + 5y(5y)

4x² - 10xy - 10xy + 25y²

4x² - 20y + 25y²

The answer is B.

440...marked down by 30% means u pay 70%
70% of 440 = 0.70(440) = 308

308 ..marked down by 10% means u pay 90%
90% of 308 = 0.90(308) = 277.20 <== price after markdowns

If a single card is drawn from a standard 52-card deck, what is the probability that it is an ace or a spade?
klasskru [66]

A 52-card deck is made up of an equal number of diamonds, hearts, spades, and clubs. Because there are 4 suits, there is a 1/4 chance to draw one of them, in our case, spades.

There are 4 aces in a 52-card deck, so the chance of drawing one is 4/52, or 1/13.

The question asks for the probability of drawing an ace or a spade. Because it uses the word "or," we add the probabilities together. This is because there is a chance of drawing either of the cards; it doesn't have to meet both requirements to satisfy the statement.

However, if the question were to say "and," we would multiply the two probabilities.

Let's add 1/4 and 1/13. First, we can find a common denominator. We can use 52 because both fractions can multiply into it (since the ratio came from a deck of 52 cards as well).

\frac{1}{4} -- > \frac{13}{52}

\frac{1}{13} -- > \frac{4}{52}

Now we can add them together.

\frac{13}{52} + \frac{4}{52} = \frac{13+4}{52} = \frac{17}{52}

This cannot be simplified further, so the probability is 17 in 52, or 33%.

hope this helps!
