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)
Answer: Option 4
Step-by-step explanation:
Each value of x maps onto only one value of y.
Answer:
38°
∠4=∠2
∠2=∠6
∠6=38°
So ∠4=38°
