Answer:

Ed used 39/60 of one hour to complete his tasks.

Step-by-step explanation:

Find the least common denominator (LCD), which would be 20

Then, find how to get from 5 to 20 and 4 to 20.

Use division.

20/5 = 4, 20/4 = 5

After this, multiply the numerator to the according number.

2*4 = 8 = 8/20

1*5 = 5 = 5/20

Make the denominator 60 to represent 60 minutes in one hour

5/20*3/3 = 15/60

8/20*3/3 = 24/60

Add the two results.

15/60 + 24/60 = 39/60

IceJOKER [234]

Answer:

What you need to do is to find a multiple of 20 and 16 in other words a number that can multiply into 20 and 16. You have 2 and you have 4. So now this is how it looks like.

Either:

4(5+4) Or

2(10+8)

...............what is (9x^2-3)^6

Lelu [443]

Step 1. Factor out the common term $3$

$(3(3 x^{2}-1)^{6}$

Step 2. Use Multiplication Distributive Property: $(xy)^{a} = x^{a} y^{a}$

 $3^{6}(3 x^{2}-1)^{6}$

Step 3. Simplify $3^{6}$ to $729$

$729(3 x^{2}-1)^{6}$

Done!
