Hi there! First, let’s convert the fractions into LCD by finding the LCM of 5 and 8, which is 40. Concert the fractions into 7 16/40 and 8 5/40. When you add both numbers, you get 15 21/40 and that is in simplest form. The sum is 15 21/40.

Difference between 1 8/10 and 2 2/5
Eva8 [605]
The first step to solving this is converting these mixed numbers into improper fractions. You would do that by multiplying the denominator by the whole number and adding the numerator to that number; this number replaces the numerator. It would look something like this:

1 8/10   -->   18/10
2 2/5   -->   12/5

Now, to subtract the second fraction from the first one, the denominators of both fractions must be the same. We can make them the same by multiplying the second fraction by 2:

12/5 * 2/2 = 24/10

Now we can set up the equation as:

18/10 - 24/10 = -6/10   -->   -3/5

The answer is negative 3/5.

I hope this helps.

factor completely 4x5 − 20x4 − 36x3. 4(x5 − 5x4 − 9x3) x3(4x2 − 20x − 36) x2 − 5x − 9 4x3(x2 − 5x − 9)
Mila [183]

Consider the polynomial 4x^5 - 20x^4 - 36x^3. It has three terms and their greatest common factor is 4x^3.

Since

4x^5=4x^3\cdot x^2,\\20x^4=4x^3\cdot 5x,\\36x^3=4x^3\cdot 9,

then

4x^5 - 20x^4 - 36x^3=4x^3(x^2-5x-9) (you write in brackets the same sign as the corresponding term has).

Answer: correct choice is D.
