Well, for method one the first step we have is distribution, then combining like terms, then property of subtraction, then division. For method two, I'm not entirely sure what they did there. I've never done math like that. Sorry I can't help you out all the way.

I see 3 right triangles.
Right triangle: a² + b² = c²
a = long leg ; b = short leg ; c = hypotenuse
hypotenuse = EH
a = 6 - 3 = 3
b = 3 - 1 = 2
c² = 3² + 2²
c² = 9 + 4
c² = 11
c = √11
c = 3.32
hypotenuse = FG
a = 3 ; b = 1
c² = 3² + 1²
c² = 9 + 1
c² = 10
c = √10
c = 3.16
hypotenuse = EF
a = 3 ; b = 2
c² = 3² + 2²
c² = 9 + 4
c² = 11
c = √11
c = 3.32
perimeter = 3.32 + 3.16 + 3.32 + 2 = 11.8
When n is the nth term in the sequence, n squared is the rule.
The next two terms are 64, 81
Good luck!
Answer:
See the image below.
Step-by-step explanation:
The decimals 0.43 and 0.39 are equivalent to 43/100 and 39/100. These decimals lie between 0 and 1.
Draw a number line, mark off and label the multiples of 0.10(e.g 0.10, 0.20) in the interval 0-1.
Mark 0.43 between 0.4 and 0.5, a little closer to 0.4.
Mark 0.39 between 0.3 and 0.4, just behind 0.4.
Since 0.39 is smaller than 0.43( 0.39 lies on the left to 0.43), the inequality is:
0.39<0.43
