Hi!
The answer is :
(y+2) * (y+9) = y^2 + 2y + 9y + 18 = y^2 + 11y + 18
Hope this helps!
Answer:
a=1.5, b= 3
Step-by-step explanation:
sum of all sides will give us perimeter. Therefore
2a+b+6a+2b+1+4a=28
12a+3b+1=28
12a+3b=27....eqn1
since t two sides of this isosceles triangle are equal:
2a+b=4a
2a=b

substituting 
in the first equation whenever we encounter a we will have:

6b+3b=27
9b=27
b=3
therefore
