What is the length of x?

Marat540 [252]

Answer:

The length of 'x' is 4

Step-by-step explanation:

We can use the pythagorean theorem to solve this.

The pythagorean theorem is:

$a ^{2} + b^{2} = {c}^{2}$

$a ^{2} + b^{2} = c^{2} \\ {3}^{2} + {b}^{2} = 5^{2} \\ 9 + {b}^{2} = 25 \\ \frac{ - 9 \: \: \: \: \: \: \: \: = - 9}{b ^{2} = \sqrt{16} } \\ b = 4$

Therefore x = 4

Robert can paint a room in 6 hours. Julio can paint a room in 8 hours.how long will it take for the two of them to paint a room

Llana [10]

Roberto paints 1/6 of a room in 1 hour.
Julio paints1/8 of a room in 1 hour.

Working together, they paint (1/6 + 1/8) = (4/24 + 3/24) = 7/24 room per hour.

The reciprocal unit rate is 24/7 hour per room = <em>3-3/7 hours</em> per room.
