I don't believe you can. It would end up being 1/2 for all the terms so just leaving it as a fraction would be neater.
Answer:
5(x^2 + 5)
Step-by-step explanation:
The binomial 5х^2 + 25 has the factor 5 in each term. Thus, in factored form, 5х^2+ 25 = 5(x^2 + 5).
Let us assume the length of the first shelf = x
Then
The length of the second shelf = 2x + 18
Length of the third shelf = x -12
Length of the fourth shelf = x + 4
The total length of the board = 2.5 meters.
= ( 2.5 * 100) cm
= 250 cm
Then we can write the equation as
x + 2x + 18 + x - 12 + x + 4 = 250
5x + 10 = 250
After dividing both sides of the equation by 5 we get
x + 2 = 50
x = 50 - 2
= 48
Then
The length of the second shelf = 2x + 18
= 2(48) + 18
= 96 + 18
= 116
So the length of the second shelf is 116 cm.
