Answer:

3+\sqrt{3} , 5\sqrt{5}, 2\sqrt{2}, and 18 -2\sqrt{2}

Step-by-Step Explanation:

1)

\sqrt{3}(\sqrt{3}+1)

Distribute the square root:

\sqrt{9}+\sqrt{3}

3+\sqrt{3}

2)

(\sqrt{5} )(\sqrt{5} )(\sqrt{5} )

\sqrt{(5)(5)(5)}

\sqrt{(25)(5)}

(\sqrt{25}) (\sqrt{5)}

5\sqrt{5}

3)

(\sqrt{2} )(\sqrt{2} )(\sqrt{2} )

\sqrt{(2)(2)(2)}

\sqrt{(4)(2)}

(\sqrt{4}) (\sqrt{2)}

2\sqrt{2}

4)

(3\sqrt{2})^{2} -2\sqrt{2}

(9)(2) -2\sqrt{2}

18 -2\sqrt{2}

If you need it factored:

2(9-\sqrt{2})

Keep in mind that square roots can be positive<em> or</em> negative.

A motorcycle zoomed along the freeway, traveling 10 meters in
Hoochie [10]

The speed of the motorcycle will be 30 meters per second.

<h3>What is speed?</h3>

The distance covered by the particle or the body in an hour is called speed. It is a scalar quantity. It is the ratio of distance to time.

We know that the speed formula

Speed = Distance/Time

A motorcycle zoomed along the freeway, traveling 10 meters in 1/3 of a second.

Then the speed of the motorcycle will be

Speed = 10 / (1/3)

Speed = 10 x 3

Speed = 30 meters per second

The speed of the motorcycle will be 30 meters per second.

More about the speed link is given below.

Solve 7x+3y=8 and 4x-y=-9 simultaneously
Jobisdone [24]

Answer: x = -1 and y = 5

Step-by-step explanation:

7x + 3y = 8 ........................... equation 1

4x - y = - 9 ............................ equation 2

Solving the simultaneous linear equation by substitution method , make y the subject of the formula from equation 2 , we have

y = 4x + 9 ............................. equation 3

substitute y = 4x + 9 into equation 1 , we have;

7x + 3 ( 4x + 9 ) = 8

7x + 12x + 27 = 8

19x + 27 = 8

subtract 27 from both sides

19x = -19

divide through by 19

x = -1

substitute x = -1 into equation 3 , we have

y = 4 ( -1) + 9

y = -4 + 9

y = 5

Therefore :

x = -1 and y = 5

Find the volume of given prism round to the nearest tenth necessary.
atroni [7]
First, find the area of the base (the triangle) and then multiply it by the height

to find the area of the triangle you need to know the height. cut the triangle in half and you get a right triangle, from there you can use the Pythagorean theorem. remember since you cut the triangle in half you have to divide one of the sides by 2

a^2 + b^2 = c^2              (plug in known information)
a^2 + (7.5)^2 = (15)^2      (solve, first solve the exponents)
a^2 + 56.25 = 225         (subtract 56.25 on both sides)
a^2 = 168.75                    (solve for a, put 168.75 under the square root)

then once you find the area multiply by the known height
