Answer:
answer is 3 1/2
Step-by-step explanation:
18/5 yard or 3 3/5 yard
Length of fabric needed for 1 costume = 3/5 yard
Length of fabric needed for 6 costumes = (3/5)*6
= 18/5 yard
= 3 3/5 yard
Answer: The correct answer is 18ft
1r
(5r-4)(2r-6r+4)
1(5r-4)+1(2r-6r+4)
5r-4+2r-6r+4
5r+2r-6=1r
1r-4+4
-4+4=0
A=4
Mariya was solving:
4x2-20x+3=0
4x2-20x=-3
A(x2-5x)=-3
At this point, we can know that 4*x2=4x2 and 4*5x=20x, son A=4
Answer: 2(15000x2)+x+600)
The third one
