An irrational number/value is one you cannot express in terms of a ration, or a fraction, it cannot be written as fraction
now 291.87... is simple, two decimals, so you use two zeros at the botom and end up with

and boom, there you are, a fraction, nice and dandy
now, let's see the first one -√(127) well, low and behold, 127 is a prime number, and and thus is has no two factors that'd serve as root, so, there's no rational root that'd give that, that makes it irrational
First you would do -30x5 which equals -150 then 2-150 equals -148

Step-by-step explanation:
.
Area of <span>parallelogram
A = bh
so
b = A/h
b = </span><span>216.24 / 15.9
</span>b = 13.6
answer
<span>base of the parallelogram = 13.9 cm</span>
3 1/2 = 7/2
so y+7/2 = 6
y=6-7/2 = 12-7 / 2 = 5/2 = 2 1/2
