Students were asked to write a trinomial that could not be factored using integers. which students followed the given directions.
pat x2 + 3x- 10
sam x2+x-12
mel x2+2x-1
lee x2+2x-3

ANSWER

Mel followed the right direction.

EXPLANATION

Pat's trinomial is;

There are factors of -10 that sums up to 3.

Hence this trinomial could be factored into (x-2)(x+5)

Sam's trinomial:

There are factors of -12 that sums up to 1.

4+-3=1

Mel's trinomial:

There are no factors of -1 that sums to 2.

This trinomial cannot be factored.

Lee's trinomial:

There are factors of -3 that sums up to 2

3+-1=2

step-by-step explanation:

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
