Solve for x over the real numbers:
2 x^2 - 4 x - 3 = 0
Divide both sides by 2:
x^2 - 2 x - 3/2 = 0
Add 3/2 to both sides:
x^2 - 2 x = 3/2
Add 1 to both sides:
x^2 - 2 x + 1 = 5/2
Write the left hand side as a square:
(x - 1)^2 = 5/2
Take the square root of both sides:
x - 1 = sqrt(5/2) or x - 1 = -sqrt(5/2)
Add 1 to both sides:
x = 1 + sqrt(5/2) or x - 1 = -sqrt(5/2)
Add 1 to both sides:
Answer: x = 1 + sqrt(5/2) or x = 1 - sqrt(5/2)
Since the scale factor is 4:3 then every dimension of triangle WXY is (3/4) of every dimension of triangle CDE.
The perimeter of triangle CDE = 13 + 22 + 29 = 64.
So, the perimeter of triangle WXY = (3/4) * 64 = 48
Idk this answer because no triangles are shaded.
The value of x which will make the provided triangles similar by the sss similarity theorem is 77.
<h3>What is SSS similarity theorem?</h3>
The SSS similarity theorem is the theorem which is used to check the two triangle are similar or not.
SSS means the side-side-side. This theorem states that if all the three sides of a triangle are proportional to the three corresponding sides of the another triangle, then the triangles are similar.
In the given image, the sides of the first triangle are 35,20 and 20. The sides of the second triangle are x, 44,44.
Thus, by the SSS similarity theorem,

The value of x which will make the provided triangles similar by the sss similarity theorem is 77.

The practical rule would be, times that number, by the result of the first time you multiplied the first number. But, it would all depend by how much your're raising the number by.
<u>
For example:</u>

We do,

But, once again, this was an example. This would show and illustrate the rule of "raising a power".<span />
