Answer:
5(5 + 2)
Step-by-step explanation:
The distributive property states that If 2 numbers have a common factor you can divide the common factor out. Similarily, if they share a common factor, you can distribute the common factor into each number in the parenthesis.
Find the factors of 25 & 10:
25: 1, 5, 25
10: 1, 2, 5, 10
Note that the largest common factor is 5. Divide 5 from both number:
(25 + 10)/5 = 5(5 + 2)
5(5 + 2) is your answer.

First you should round the numbers that you are multiplying so.
56 ---> 60
27---> 30
You know that 5 and higher you'll round up.
4 and below you'll round down.

Answer:
The length and width of the pool = 24 ft and 16 ft
Step-by-step explanation:
Let length of pool be l and width of pool be w.
A pool in the shape of a rectangle has a perimeter of 80feet.
Perimeter of pool = 2 x ( l + w ) = 80 feet
That is
l + w = 40 ft -----------------------------------eqn 1.
The pool is 8 feet less wide than it is long.
l = 8 + w
l - w = 8 ft -----------------------------------eqn 2.
eqn 1 + eqn 2
2 l = 48
l = 24 ft
Substituting
24 + w = 40
w = 16 ft
The length and width of the pool = 24 ft and 16 ft
