An equilateral triangle has a side length measure that is represented by 2x+4. What is the perimeter of the triangle? And how wo
uld i show this in a model?
2 answers:
The perimeter is 6x + 12, and a model example is attached.
All three sides of an equilateral triangle are the same, so multiply the side length by 3 to find the perimeter.
3(2x + 4)
Now distribute the 3.
3 * 2x + 3 * 4
6x + 12
6x+12 is P
All sides are same so add up (2x+4)+(2x+4)+(2x+4)

The last option
Step-by-step explanation:
You take the middle 2 numbers, add them up, and divide by 2.
So y^2 times 9^5 or
y*y means y times y so
y*y*9*9*9*9*9 or 59049y^2
