If 5(x - 4) + 2 = -173, what is the value of x

5x-20+2= -173
5x-18= -173
5x= -155
x= -31
First, you multiply everything in parentheses by 5 and then add the 2. Next, you subtract 20-2 which will give you -18. Then, you add 18 to both sides which will give you -155. Finally, you divide -155 by 5 to give you a final answer of -31.

Answer:
x = -31

Explanation:
To get the value of x, we will need to isolate the x on one side of the equation.
This can be done as follows:
5(x-4) + 2 = -173

1- get rid of the brackets:
5x - 5(4) + 2 = -173
5x - 20 + 2 = -173

2- Combine like terms:
5x - 20 + 2 = -173
5x - 18 = -173
5x = -173 + 18
5x = -155

3- Get rid of the coefficient of the x:
5x = -155
x = -155/5
x = -31

Hope this helps :)

Prove that a triangle with the sides a - 1 cm to root under a

vivado [14]

Question is Incomplete, Complete question is given below.

Prove that a triangle with the sides (a − 1) cm, 2√a cm and (a + 1) cm is a right angled triangle.

Answer:

∆ABC is right angled triangle with right angle at B.

Step-by-step explanation:

Given : Triangle having sides (a - 1) cm, 2√a and (a + 1) cm.

We need to prove that triangle is the right angled triangle.

Let the triangle be denoted by Δ ABC with side as;

AB = (a - 1) cm

BC = (2√ a) cm

CA = (a + 1) cm

Hence,

${AB}^2 = (a -1)^2$

Now We know that

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

So;

${AB}^2= a^2 + 1^2 -2\times a \times1$

${AB}^2 = a^2 + 1 -2a$

Now;

${BC}^2 = (2\sqrt{a})^2= 4a$

Also;

${CA}^2 = (a + 1)^2$

Now We know that

$(a+ b)^2 = a^2+b^2 + 2ab$

${CA}^2= a^2 + 1^2 +2\times a \times1$

${CA}^2 = a^2 + 1 +2a$

${CA}^2 = AB^2 + BC^2$

[By Pythagoras theorem]

$a^2 + 1 +2a = a^2 + 1 - 2a + 4a\\\\a^2 + 1 +2a= a^2 + 1 +2a$

Hence, ${CA}^2 = AB^2 + BC^2$

Now In right angled triangle the sum of square of two sides of triangle is equal to square of the third side.

This proves that ∆ABC is right angled triangle with right angle at B.
