Factor each polynomial. Look for a GCF first (i don’t know how to get the GCF and the circled numbers are what ones i have to do)

20.

22.

24.

Step-by-step explanation:

20.

The GCF is x, so you group it out of the equation first.

Then, you find 2 numbers that will equal to 2 when you add them and will equal to -48 when you multiply them.

The two numbers would be -6 and 8. You then differentiate the squares.

22.

The GCF is 2, so you must group it out.

Find the two numbers that will equal to 5 when you add them and will equal to 4 when you multiply them.

The two numbers would be 1 and 4. Finally, differentiate the squares.

24.

The GCF is 5m, so you must group it out.

Find the two numbers that will equal to 6 when you add them and will equal to -7 when you multiply them.

The two numbers would be -1 and 7. Finally, differentiate the squares.

30 miles

step-by-step explanation:

we know that 60 seconds equals 1 minute and 60 minutes 1 hour

44 ft       60 sec     60 min     158400   ft

  *   *   =

1 sec       1 min       1 hour         hour

we know that there are 5280 ft per mile

158400   ft       1 mile         30 miles

  *   =

1   hour               5280 ft     1 hour

so in 1 hour   it can travel 30 miles

24+x=y
