Answer:
Step-by-step explanation:
The Pythagorean Theorem states that

or that the two legs added together squared equal the hypotenuse squared
not: this only works with right triangles
Now Pythagorean triples are the set of sides that follow that rule
an example would be 3,4,5
why is it a Pythagorean triple?
well because it follows


25=25
Answer: the area of the triangle = 10.5 cm²
Step-by-step explanation:
Let 3x=a, 4x=b, 5x=c.
Hence,
P=2*(a+b+c)
36=2*(3x+4x+5x)
36=2*12x
36=24x
Divide both parts of the equation by 24:
1.5 cm=x
a=3x
a=3*1.5
a=4.5 cm
b=4x
b=4*1.5
b=6 cm
c=5x
c=5*1.5
c=7.5 cm

1. Add 9
2. Add 1/3
3. Add 15
2x + 5 > 3x + 1
<u> - 2x - 2x </u>
5 > x + 1
<u>- 1 - 1</u>
4 > x
x < 4
