-8n+4(1+5n)=-6n-14 solve
Tasya [4]

Answer:

n = - 1

Step-by-step explanation:

Given

- 8n + 4(1 + 5n) = - 6n - 14 ← distribute and simplify left side

- 8n + 4 + 20n = - 6n - 14

12n + 4 = - 6n - 14 ( add 6n to both sides )

18n + 4 = - 14 ( subtract 4 from both sides )

18n = - 18 ( divide both sides by 18 )

n = - 1

<h2><u>EQUATIONS</u></h2>

We'll solve this equation:

<h3>5x + 17 = 4(3x - 1)</h3>

First, let's apply the distributive property:

‎      ‏‏‎5x + 17 = 4(3x - 1)

‎      ‏‏‎5x + 17 = 12x - 4

Now, add 4 to both sides of the equation:

‎      ‏‏‎5x + 17 = 12x - 4

5x + 17 + 4 = 12x - 4 + 4

‎      ‏‏‎5x + 21 = 12x

Substract 5x from both sides:

‎  ‎     ‏‏‎5x + 21 = 12x

5x - 5x + 21 = 12x - 5x

‎      ‏‏‎‎      ‏‏‎‎   21 = 12x - 5x

‎      ‏‏‎‎      ‏‏‎‎   21 = 7x

Now, divide both sides by 7

‎      ‏‏‎‎   21 ÷ 7 = 7x ÷ 7

<h3>‎      ‏‏‎‎   ‎    ‏‏‎‎ 3 = x</h3>

Therefore, x = 3.

‎      ‏‏‎‎    

<h3>B. The equation has one solution.</h3>

For this case what we must do is use the cosine theorem to solve the problem.
 We have then:
 c ^ 2 = a ^ 2 + b ^ 2 - 2abcos (x)&#10;
 Where,
 a, b, c: are the sides of the triangle.
 x: is the angle between the sides a and b of the triangle.
 Substituting values we have:
 c ^ 2 = 90 ^ 2 + 75 ^ 2 - 2 (90) (75) cos (85)&#10;
 Clearing c we have:
 c =  \sqrt{90 ^ 2 + 75 ^ 2 - 2 (90) (75) cos (85)}
 Answer:
 
option 1
 
c = \sqrt{90 ^ 2 + 75 ^ 2 - 2 (90) (75) cos (85)}

Can anyone help me with this question please. <br> I’ll mark as a brainliest.
Dimas [21]

Answer:

Hypotenuse

Step-by-step explanation:

We have the Pythagorean Theorem.

In simple terms, the Pythagorean Theorem can be explained by one equation.

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

a and b being the legs while c being the hypotenuse.

Looking at the sentence, we can see that hypotenuse is our answer.
