The answer is 4p i believe. (3+5p) is 8 and (1-5p) is -4, so 8p - 4p is 4p
<span>x-y=2y -> x=3y and
3x-40+2y=180 --> 9y-40+2y=180 --> 11y=220 --> y=20, x=60 --> <A=<C=140 degrees, <B=<D=40 degrees.</span>
The irrational numbers are: √8, √10 and √15
Step-by-step explanation:
A rational number is a number that can be written in the form p/q where p&q are integers and q≠0.
"All the numbers whose square root is not a whole number and has an infinite number of digits after decimal, are irrational numbers"
So in the given options

Which can be written in the required form so √4 is a rational number

√8 has an infinite expansion hence it cannot be written in the p/q form, so it is an irrational number

√10 has an infinite expansion hence it cannot be written in the p/q form, so it is an irrational number

√15 has an infinite expansion hence it cannot be written in the p/q form, so it is an irrational number

Which can be written in the required form so √36 is a rational number
Hence,
The irrational numbers are: √8, √10 and √15
