1/2 = 2/4 = 3/6 = 4/8 = 5/10 = 6/12
Let's think of this visually, as a pie.
If you were to split a pie down the middle into two pieces and ate one slice, you would be eating half of it.
Now, let's say you didn't eat one of those slices. You sliced the pie down the middle (vertically) and made another slice (horizontally). You would have 4 equal pieces. If you ate two slices that were side by side, you would still have had the same amount if you just sliced it once. If you were to keep slicing and eating, you'd be eating the same amount if you kept it to two pieces.
Hope it helped!

Define x :
--------------------------------------------------------------------
Let the smallest number be x.
First number = x
Second Number = x + 1
Third Number = x + 2
--------------------------------------------------------------------
Construct equation :
--------------------------------------------------------------------
x(x+2) - (x+1) = 7(x+2) + 1
--------------------------------------------------------------------
Solve x :
--------------------------------------------------------------------
x(x + 2) - (x + 1) = 7(x + 2) + 1
x² + 2x - x - 1 = 7x + 14 + 1
x²- 6x - 16 = 0
<span>(x+2)(x-8) = 0
</span>x = -2 or x = 8
Since x is a positive integer, it cannot be negative.
⇒x = 8

Answer:
6.43
pls follow me and mark brainliest ...thank u
Step-by-step explanation:
length of side x will be
Tan tita = opp/adjacent
tan65 = x/3
tan 65 is 2.14
so...you are left with 2.14=x/3
by cross multiplying
x= 2.14 × 3
= 6.43
