2x² - 4x - 2 = 0 <=> 2(x² - 2x - 1 ) = 0

<=> 2(x² - 2.x.1 - 1² ) = 0 <=> 2(x - 1)² = 0

<=> (x - 1)² = 0/2 = 0 <=> x - 1 = 0

<=> x = 0 + 1 = 1

P/s: A² - 2AB + B² = (A - B)²

ANSWER: x = 1

Ok done. Thank to me :>

Help asaaaap explain please!!!!!

mariarad [96]

Answer:

Step-by-step explanation:

Once

$\sqrt{xy} = 6$

We know that $xy = 36$

There are infinity values for $x, y$ , but considering $x, y \in \mathbb{Z}$

Below we have all the solutions for $x, y$

Negative:

$\\x = -36 \text{ and } y = -1\\x = -18 \text{ and } y = -2\\x = -12 \text{ and } y = -3\\x = -9 \text{ and } y = -4\\x = -6 \text{ and } y = -6\\x = -4 \text{ and } y = -9\\x = -3 \text{ and } y = -12\\x = -2 \text{ and } y = -18\\x = -1 \text{ and } y = -36\\$

Positives:

$x = 36 \text{ and } y = 1\\x = 18 \text{ and } y = 2\\x = 12 \text{ and } y = 3\\x = 9 \text{ and } y = 4\\x = 6 \text{ and } y = 6\\x = 4 \text{ and } y = 9\\x = 3 \text{ and } y = 12\\x = 2 \text{ and } y = 18\\x = 1 \text{ and } y = 36\\$

We can see that $x + y \neq 18$

Answer:

Since this means f of g so I will get the function g(x) and replace it with X in the function of f (x)

If you have a lowest score of 21 and a range of 47, your highest score will be:________

aalyn [17]

Answer: 68

Step-by-step explanation:

range=47 lowest score = 21 let highest score =x

Range=highest score - lowest score

47 = x - 21

x = 47 + 21

x = 68

Therefore the highest score is 68

A rabbit can run 35 miles per hour.A fox can run 21 miles in half an hour.Which animal is faster and how much

Pachacha [2.7K]

Answer:

Step-by-step explanation:

The fox is faster. Because he is a fox.

Also because he can (assuming he doesn't fatigue or get caught by hounds in the second half of the hour) run 42 miles in 1 hour.

The rabbit runs 35 miler per hour.

Velocity = Distance/time

Fox velocity = 21 miles/0.5 hour

Dividing by 0.5 is the same as multiplying by 2, so...

Fox velocity = 42 miles/hour
