I hope this somewhat helped you find your answer.
Answer:
2sqrt(10)
Step-by-step explanation:
radical 40
I rewrite this as sqrt(40) It means the same thing
sqrt(40)
sqrt(4*10)
We know that sqrt(a *b) = sqrt(a) sqrt(b)
sqrt(4) sqrt(10)
2sqrt(10)
Answer:
Last one 2 7/9
Step-by-step explanation:
If the baker made 5 pounds of icing and used 4/9 of the icing to make decorations, then he used:
5 * 4/9 =
= 20/9 =
= 2 2/9 [of icing]
To find out how much he has left over, we just need to substract 2 2/9 from 5:
5 - 2 2/9 =
= 3 - 2/9 =
= 2 7/9
7y-3=5y+3
2y=6
y=3
so the length of XY = 7*3-3 =18
