Answer:

\sqrt{29} +\sqrt{5} = 7.6 miles

Step-by-step explanation:

\sqrt{(2+3^2)+(3-2)^2} +(\frac{\sqrt{(4-2)^2+(-1-3)^2} }{2} )

\sqrt{29} +\frac{2\sqrt{5} }{2}

\sqrt{29} + \sqrt{5}

equals 7.6 (rounded to nearest tenth)

Two side lengths of a triangle are given as 9 cm and 5 cm. What could be the length of its third side? 3cm
disa [49]

The length of the third side could be 5 cm ⇒ 3rd answer

Step-by-step explanation:

There is a fact in any triangle, that the sum of the lengths of the

smallest two sides of a triangle must be greater then the length of

the largest side

The sum of smallest 2 sides > the 3rd side

So to solve the problem

1. Chose the third side from the answer

2. Add the lengths of the two smallest side

3. Compare between the sum and the 3rd side

∵ The length of the two sides of a triangle are 9 cm and 5 cm

- If the third side is 3 cm

∵ 3 and 5 are the smallest side

∵ 3 + 5 = 8

∵ 8 < 9

∴ The sum of the smallest two sides < the 3rd side

∴ 3 cm can not be the length of the 3rd side

- If the third side is 4 cm

∵ 4 and 5 are the smallest side

∵ 4 + 5 = 9

∵ 9 = 9

∴ The sum of the smallest two sides = the 3rd side

∴ 4 cm can not be the length of the 3rd side

- If the third side is 5 cm

∵ 5 and 5 are the smallest side

∵ 5 + 5 = 10

∵ 10 > 9

∴ The sum of the smallest two sides > the 3rd side

∴ 5 cm can be the length of the 3rd side

- If the third side is 14 cm

∵ 5 and 9 are the smallest side

∵ 5 + 9 = 14

∵ 14 = 14

∴ The sum of the smallest two sides = the 3rd side

∴ 14 cm can not be the length of the 3rd side

The length of the third side could be 5 cm

Simplify the expression.<br><br> 8k - 2(4 - 3k)
DIA [1.3K]

Answer:

14k-8

Step-by-step explanation:

8k - 2(4-3k)

distributive property

8k - 8  + 6k

add like terms

8k + 6k -8

14k - 8

14k - 8

If anyone will look for the value of k, k is 4/7 btw but the answer to simplify the expression would be 14k-8.

Factor x3y6 + 27z42. (xy3 + 3z39)(x2y9 – 3xy3z39 + 9z1,521) (xy3 + 3z39)(x2y6 – 3xy3z39 + 9z78) (x3y6 + 27z42)(x6y12 – 27x3y6z42
Licemer1 [7]

Answer:

x^3y^6 + 27z^{42} = (xy^2 + 3z^{14})(x^2y^4 - 3xy^2z^{14} + 9z^{28})

Step-by-step explanation:

Given

x^3y^6 + 27z^{42

Required

Factor

Express both terms as a cube

x^3y^6 + 27z^{42} = (xy^2)^3 + (3z^{14})^3

Let

a =(xy^2)

b = (3z^{14})

So:

x^3y^6 + 27z^{42} = a^3 + b^3

Using sum of cubes:

a^3 + b^3 = (a + b)(a^2 - ab + b^2)

So:

x^3y^6 + 27z^{42} = (a + b)(a^2 - ab + b^2)

Substitute in, values of a and b

x^3y^6 + 27z^{42} = (xy^2 + 3z^{14})((xy^2)^2 - (xy^2)*(3z^{14}) + (3z^{14})^2)

x^3y^6 + 27z^{42} = (xy^2 + 3z^{14})(x^2y^4 - 3xy^2z^{14} + 9z^{28})
