Sam drew a square with each side being exactly 12 centimeters long. If he wanted to make the square 12% larger which expression can be use to find the new sides length?
A. 12 x 0.12
B. 12 + 1.12
C. 12 x 1.12
D. 12 +0.12

A. 12 × 0.12

Step-by-step explanation:

Understanding the concept

When you want to make something bigger, it means multiplying it. And percentage (%) can be written as the times sign (×).

Simplifying

We already have 12.

If you simplify this, you would end up with:

Then, 12 × 0.12

Therefore, option A is the expression.

5050

hope this !

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)
