P = 2(L + W)
P = 2(12 + 8)
P = 2(20)
P = 40.....so there is 40 meters of fence around the pool. If a post was placed every 2 meters, then u would have (40 / 2) = 20 posts <=

Maggie's brother is three years younger than twice her age. The sum of their ages is 24 how old is maggie?
Vanyuwa [196]

The variable for Maggie will be M and 2x-3 be her younger brothers age (<u>Twice her age). </u>We then would turn this into <u>an algebraic problem</u>. (m+2x -3=24).

3x-3=24, we would add 3 to both sides (-3 and 24). 24 + 3 equals 27, we now have to divide -3x and 27 on both sides, which equals <u>9. (x=9)</u>
