Write the polynomial as a product
3m–mk+3k–k2
giving 20 points need

  (3 -k)(m +k)

Step-by-step explanation:

Group the terms in pairs, factor each pair, then pull out the common factor from that result.

  (3m -mk) +(3k -k²)

  = m(3 -k) +k(3 -k) . . . . . (3-k) is a factor common to both terms

  = (3 -k)(m +k)

the answer is c. 23/3

answer: bearing in mind that a rectangle has a perimeter of length + length + width + width.

step-by-step explanation:

p = perimeter

l = length

x=width

p = 2l + 2x

p = 2(l+x)     < ==== perimeter of the base of the box.
