The Sweetings are building an ornamental garden pond. They intend to lay 1m square slabs around its perimeter. If the pond is 8m by 8m, how many slabs will they need?

32 slabs are needed

Step-by-step explanation:

If the pond is 8m by 8m, then that means each side is equal, and each side is 8m long. There are 4 sides to the perimeter of the pond. To find how many slabs you need, you need to found out how many meters long the perimeter of the pond is in total. To do so, you must multiply the length of one side of the perimeter to the number of sides there is. The length of one side of the perimeter is 8m, and the number of sides is 4, which means you must multiply 8 by 4, which equals 32.

answer: x=60

you didn't post any answer choices, so its not 100% clear what your teacher is looking for

however, log(15/7) is equivalent to log(15) - log(7)

i'm using the rule log(x/y) = log(x) - log(y)
