Yeah sometimes I forget these things too.
Just add what’s in the bracket then square it.
(6+1)^2
7^2

I’m pretty sure the last answer is the correct one!
Answer:
Step-by-step explanation:
The top triangle is similar to the whole triangle because of AAA
Then we know that the corresponding sides are similar
9/81=(3x-20)/(3x-20+56)
1/9=(3x-20)/(3x+36)
cross multiply
9(3x-20)=3x+36
27x-180=3x+36
24x=216
x=9
Answer:
56 because you have to multiply 28 times 2
Are there any opinions? i need to know to help you out, theres not much to go by:(
