I need help plz help me

Step-by-step explanation:

It appears to be the last step there that has evaded you.  In the second line of work, you can see that what's in each set of parenthesis is exactly the same.  Because of this, it is common and can be factored out.  What's left is the 4x and the +5:

(5x - 3)(4x + 5)

That's factoring by grouping.  It only works with polynomials that have an even number of terms so you can group them together in 2's.

connie < felicia < stew

step-by-step explanation:

stew:

we need to find the slope

m = (y2-y1)/ (x2-x1)

    = (2650-795)/(10-3)

    = 1855/7

connie:

we need to find the slope

m = (y2-y1)/ (x2-x1)

we have two points (0,0) and (4,800)

m = (800-0)/(4-0)

  m = 800/4

felicia:

260 words per minute

200< 260 < 265

connie < felicia < stew
