Answer:
Let x = the third side
In a triangle, the sum of any 2 sides must be larger than the third side.
I believe this is called the triangle inequality theorem.
We can construct 3 inequalities to obtain the range of values for the third side.
(Inequality #1) 12 + 4 > x
16 > x
(Inequality#2) 12 + x > 4
x > -8 (we can discard this ... we know all sides will be positive)
(Inequality #3) 4 + x > 12
x > 8
So when we combine these together,
8 < x < 16
X (the third side) must be a number between 8 and 16. but not including 8 and 16
What figures are you talking about, can you post the picture?
Answer:
n = 60
Step-by-step explanation:
<em>Terms which are divisible by 9 between 60 and 600.
</em>
<em>
63, 72, 81, ........ 594
</em>
<em>
n = [ (l - a)/d ] + 1
</em>
<em>
n = [(594 - 63)/9] + 1
</em>
<em>
n = (531/9) + 1
</em>
<em>
n = 59 + 1
</em>
<em>
n = 60</em>
