The answer to this question would be 39..here is why:
First you multiply 23 x 3..because multiplication or division always comes before addition or subtraction.
Second, you get the product from 23 x 3 which is 69..and you subtract 30 from that.
Last, after you do that you get an over all answer of 39..
Hope this helps!!
Answer:
C. DE=52
Step-by-step explanation:
Because the triangle is equilateral (all sides being equal), the half of each side is equal to the sides of the smaller triangle. Since BC=26, DE would be double.
the common difference is two of course
The area of what? if those are the dimensions of a triangle, you would do base times height divided by 2.
You find the circumference of a full circle so 2πr =43.98
then divide by 4=10.995
so the answer is 10.995cm
