Answer:
C - 45 is the LCM of 15 & 45
Step-by-step explanation:
Find the multiples:
15, 30, 45, 60
45, 90
They both have 45 in common
Actually I can help you in three of them as the number "3" is not confined between the arrays ND and NE
So:
It would be
angle END
or
angle DNE
or
angle N
Answer:
Hello,
I believe that your answer is A. (250,100)
Hope this helps
Assign the following variables for the origina3l rectangle:
let w = width let w + 8 = length and the area would be w(w + 8) = w² + 8w
No for the second rectangle:
let (w + 4) = width and (w + 8 - 5) or (w + 3) = length
Area = length x width or (w + 4)(w + 3) = w² + 3w + 4w + 12 using the foil method to multiply to binomials. Simplified Area = w² + 7w + 12
Now our problem says that the two area will be equal to each other, which sets up the following equation:
w² + 8w = w² + 7w + 12 subtract w² from both sides
8w = 7w + 12 subtract 7w from both sides
w = 12 this is the width of our original rectangle
recall w + 8 = length, so length of the original rectangle would be 20
The answer is C. 30.5% :)
