What is the solution of Vx2+49 V x2+49 - x+5?

Mathematics
1 answer:
balu736 [363]3 years ago
3 0

Answer:

x = \frac{12}{5}

Step-by-step explanation:

Given,

\sqrt{x^{2}+49 } = x + 5

Squaring on both L.H.S. and R.H.S.

\sqrt{(x^{2}+ 49 )} ^{2} = (x + 5)^{2}

By expanding L.H.S. we get x² + 49

By expanding R.H.S. we get x² + 10x + 25

x² + 49 =  x² + 10x + 25

x² will be subtracted:

49 = 10x + 25

Variables are to be arranged:

10x = 49 - 25

10x = 24

x = \frac{24}{10}

∴ x = \frac{12}{5}

What are the areas of each smaller rectangle and the large rectangle?
zhannawk [14.2K]

Answer:

Area of part 1: 3 * 5\sqrt{2} = 15\sqrt{2}

Area of part 2: 3\sqrt{2} * 5\sqrt{2}=30

Area of entire rectangle: 30 + 15\sqrt{2}

Step-by-step explanation:

The area of a rectangle can be found by using formula : length * width.

The area of part 1 can be simplified to this:

3 * 5\sqrt{2} = 15\sqrt{2}

Area of part 2:

3\sqrt{2} * 5\sqrt{2}=30

The area of the entire rectangle can simply be added from part 1 and part 2.

For area 2, remember multiplying the square root of 2 twice nullifies the square root. So it becomes 15 * 2, which is equal to 30.

kelly is using a bucket to fill up a barrel with water from a well. The barrel holds 25.5 liters.the bucket holds 800 millileter
SVEN [57.7K]
To determine how much of the barrel is left to fill, you must subtract the amount of water already in it from the total mass of the bucket. 

25.5 - 5.2 = 20.3 Litres  

In order to the fill the entire barrel, Kelly must collect 20.3 Litres of water. You must then covert the measurement from litres to millilitres so that the bucket and barrel are measured in the same units. 

20.3L = 20300mL

You must then divide the amount of space left by the mass of the bucket. This will determine the least number of buckets needed to fill the barrel. 

20300 <span>÷ 800 = 25.375 

That means the you would have to do a minimum on 25.375 buckets to fill the barrel, or 26. 

Hope this helps :) </span>
