An equilateral triangle sides are all equal to each other. This means that is one side of an equilateral triangle is x + 3 then the sides of the other two triangles as also each x + 3
The formula for perimeter of a triangle is:
Perimeter = side 1 + side 2 + side 3
Or in the case of an equilateral triangle it would be:
Perimeter = 3(side)
This means that for the formula of this equilateral triangle you have:
Perimeter = 3(x + 3)
If asked the three out side of the parentheses can be distributed, meaning that you multiply the outside number (in this case that is 3) to all the number inside the parentheses (in this case that is x and 3)
Perimeter = (3 * x) + (3*3)
Perimeter = 3x + 9
Both of these are correct:
P = 3(x + 3)
P = 3x + 9

Answer:
A.
Step-by-step explanation:
when you distribute it you keep the subtraction sign and have to multiply 6 by 50 and then 6 by 1
This is the answer: <span>x2 + 5x + 6 = </span><span>(x + 2)(x + 3)</span>
Answer:
No
Yes
No
Explain:
The ballon thing is getting longer if we fly them, so we can not accelerate it.
The length of the triangle doesn't change.
Paper airplane does shrinks, so the answer is no.
32, 60, 68
