A farmer is able to prepare 1/2 are of soil in 3 days. How long will it take him to prepare 2 1/4 acres of soil?
Alexxx [7]

Answer:

x = 13 1/2 days

Step-by-step explanation:

1/2 acre              2 1/4 acre

------------ = -------------------------

3 days           x days


using cross products

1/2 * x = 2  1/4 * 3

change 2  1/4 to an improper fraction   (4*2+1)/4 =9/4

1/2 x = 9/4*3

1/2x = 27/4

multiply each side by 2

2 * 1/2 x = 27/4 * 2

x = 27/2

change back to a mixed number

x = 13 1/2

Plz fast plzzzzzzzz ​
scoray [572]

Step-by-step explanation:

cubing both sides (p+1)^3= (7)^3

=> p^3+1/p^3+ 3(p+1/p) = 343

=> p^3+ 1/p^3 + 3(7)= 343

=> p^3+1/p^3= 343-21

=> p^3+1/p^3= 322

Let f(x) = x + 7 and g(x) = x − 4. Find f(x) ⋅ g(x).
saveliy_v [14]

For this case we have the following functions:

f (x) = x + 7\\g (x) = x-4

We must find the product of the functions:

f (x) * g (x) = (x + 7) (x-4)

We apply distributive property:

f (x) * g (x) = x ^ 2-4x + 7x-28\\f (x) * g (x) = x ^ 2 + 3x-28

Finally, the product of the functions is:

x ^ 2 + 3x-28

Answer:

x ^ 2 + 3x-28
