Calculate the perimeter of an equilateral triangle of side 3cm

P=9cm

Step-by-step explanation:

When the triangle is equilateral, it means that all sides are equal. In this case, all three sides are 3cm.

The equation to find the perimeter for a triangle is just to add all sides.

This becomes:

3+3+3=9.

So, in conclusion, the perimeter of this equilateral triangle is 9cm.

Hope this helps, and have a nice day:)

step-by-step explanation:

divide the cost of the total of sodas you bought by the cost of one soda, for example:

$24.57 divided by $1.89 is 13 which means you bought 13 sodas

the answer is:

the correct option:

b.

to solve the problem, we need to remember how to operate to simplify exponential expressions using the logarithms.

we are given the equation:

then, using placing logarith with base 7 on both sides of the equation, we have:

so, rounding the obtained result to two decimal places (nearest hundreth), we have:

hence, we have that the correct option:

b.

have a nice day!
