I assume the question asks to expand the expression to individual terms.
There are different ways to approach this, all based on FOIL or similar methods.
I prefer to split it into two parts, as follows:
(x+y+2)(y+1)
=x(y+1)+(y+2)(y+1)
=xy+x+y^2+3y+2
Answer:
32
Step-by-step explanation:
even numbers are 2,4,6,...,78
it is an A.P.
first term a=2
c.d. d=4-2=2
an=a+(n-1)d
78=2+(n-1)2
76=(n-1)2
n-1=76/2=38
n=38+1=39
now we take multiples of 10
10,20,30,...,70
70=10+(n-1)10
60=(n-1)10
n-1=60/10=6
n=6+1=7
so reqd. number of numbers=39-7=32
