The perimeter of a rectangle is 60 m and its length is twice its width. find the length of the rectangle

GREYUIT [131]

Length = 2W

P= 2L + 2W
60 = 2(2W) + 2W
60= 4W +2W
60 = 6W
60/6W = 6W/6W
w = 10
Length = 2(10)
Length = 20

P= 2L + 2W
60= 2(20) + 2(10)
60= 40 +20
60 = 60

Find the value of the missing coefficient in the factored form of 27f^3 + 125g^3. 27f^3+125g^3=(3f+5g)(9f^2-?fg + 25g)^2

7nadin3 [17]

Answer:

Step-by-step explanation:

The formula for factoring a sum of cubes is:

$a^3+b^3=(a+b)(a^2-ab+b^2)$

We have a=3f and b=5g here.

So a*b in this case is 3f*5g=15fg.

The ? is 15.
