Answer:
3x^2+27y^2-18xy
Step-by-step explanation:
3(x-3y)^2
3 [(x-3y)(x-3y)]
3 [x^2-3xy-3xy+9y^2]
3 [x^2-6xy+9y^2]
open d bracket
3x^2-18xy+27y^2
rearrange
3x^2+27y^2-18xy
Answer:
24 spaniels
Step-by-step explanation:
4 many spaniels as retriever means that if you put the dogs in the correct order, every 5 animals you will have one retriever and 4 spaniels, then one retriever and four more spaniels. That is, there are groups of 5 dogs with that ratio. If there are 30 dogs, you can make 6 of these groups. It means that you have 24 spaniels and 6 retrievers.
It’s for sure B the formula for circumference is
Pi times the diameter and the diameter is double the radius so it’s pi multiplied by 8
Answer:
12
Step-by-step explanation:
5/6 x 2/2 = 10/12
1/4 x 3/3 = 3/12
2/3 x 4/4 = 8/12
5/6 + 1/4 = 13/12 (over 1 yard)
1/4 + 2/3 = 11/12 (slightly less than 1 yard)
5/6 + 2/3 = 18/12 (too much)
Here is the answer for a:
a) 5/6 and 1/4
