1. squaring
2. four triangles and the square with side length "c"
3. big square (side length: a+b)
First combine like terms
6c + 14 = 4c + 4, then subtract 4c from both sides
2c + 14 = 4, then subtract 14 from both sides
2c = -10, then divide both sides by 2
C = -5
Answer:
2x^2 = 6x - 5.
-x^2 - 10x = 34.
These have only complex roots/
Step-by-step explanation:
3x^2 - 5x = -8
3x^2 - 5x + 8 = 0
There are complex roots if the discriminant 9b^2 - 4ac) is negative.
Here the discriminant D = (-5)^2 - 4*-5*8 = 25 + 160
This is positive so the roots are real.
2x^2 = 6x - 5
2x^2 - 6x + 5 = 0
D = (-6)^2 - 4*2*5 = 36 - 40 = -4
So this has no real roots only complex ones.
12x = 9x^2 + 4
9x^2 - 12x + 4 = 0
D = (-12)^2 - 4*9 * 4 = 144 - 144 = 0.
- Real roots.
-x^2 - 10x = 34
x^2 + 10x + 34 = 0
D = (10)^2 - 4*1*34 = 100 - 136 = -36.
No real roots = only complex roots.
Since the sum of any two sides is greater than the third, hence the three sides for the sides of a triangle
<h3>What is a triangle?</h3>
A triangle is a 2-D shape with 3sides and angles. According to the question, we are to determine whether the given measures form sides of a triangle.
For the following measure to form the sides of a triangle, the sum of any two sides must be equal to the third as shown:
3 + 12 = 15 > 13
3 + 13 = 16 > 12
13 + 12 = 25 > 3
Since the sum of any two sides is greater than the third, hence the three sides for the sides of a triangle
