What is the surface area of the faces of the pyramid?
Alekssandra [29.7K]
The area of a triangle is (base*height)/2
Therefore: 12*10=120/2=60. Since there are three triangles then you multiply 60 by three. 60*3=180
Since the triangle in the middle is equilateral the height is 10. (10*10)/2=50
180+50=230
The answer is 230 inches²

2 ^ 3 * 3 ^ 6 / 3 ^ 4 pls​
lesya [120]

Answer:

72

Step-by-step explanation:

2^3x3^6= 5832

5832/3^4=72

(You could very well solve this on a T84 calculator, there are apps that simulate it on the phone I believe, but if you do not have a phone I am sure you could find a website that could do the job just as well! Good luck with the work! ^-^)

Which of the descriptions is true for the graph
Flura [38]

Let's check every choices until one choices satisfy the graph :

Choice A is just a translation of -5 units or 5 units to the left

If we look at the graph between A"B"C" and A'B'C'

A"B"C" is 5 units to the left of A'B'C'

Therefore Choice A is True!

The correct answer is A.

No need to check for the other choices since you got a true statement at the first Choice.

IF in case that A is False, then you need to check the other choices.
