Hi.
In an equilateral triangle, as the name implies, all the sides are equal in length.
You find perimeter by adding all the sides.
The formula for perimeter is 3<em>a </em>where <em>a</em> = the length of the side.
3(12) = 36 cm
The perimeter of the triangle is 36 cm.

3x-25=14
First, you'll add the 25 to the other side of the equation because its negative. 25+14 =39. then you'll divide these by 3. (because it says 3 times what curtis spent.)
39÷3=13. so the answer is 13. curtis spent 13 dollars shopping.
Answer:
(D) 
Step-by-step explanation:
The quadratic formula is:
Assuming that a is our x² term, b is our x term, and c is the constant, we can substitute inside the equation.
So the answer is D, .
Hope this helped!
Third one. Product is the answer you get when multiplying. So 22x49= 1078
Answer: 1.3 hours
Step-by-step explanation: I believe it’s 1.3 hours since Pump A can fill a tank in 8 hours, and Pump B can fill a tank in 6 hours, then you divide 8 and 6 which is about 1.333.
