Answer:

perimeter is 12x-6

Step-by-step explanation:

perimeter is the sum of all sides

3(x+2) + 2x+11 + 7x-23

distribute the 3 in the first term, then combine 'like terms'

3x+6 + 2x+11 + 7x-23

3x+2x+7x + 6+11+(-23)

12x-6

Three friends share a pizza.one eighth falls on the fall and is thrown away.the remainder is shared equally..what fraction of th
maria [59]
If one eighth of the pizza falls, that leaves seven eights of the pizza to be shared:

1\ (whole\ pizza) -\frac{1}{8}=\frac{7}{8}

If the 7/8 pizza is shared between three people, then you have to divide 7/8 by 3. We know that dividing a fraction by 3 is the same as multiplying by 1/3:

\frac{7}{8} \div 3\\\\\frac{7}{8}*\frac{1}{3}\\\\\frac{7*1}{8*3}\\\\frac{7}{24}

Therefore, each person gets 7/24 of the whole pizza.
