pleaseeee help!!!!! will give brainlist

For the equations, you could say numerous examples such as 3( 2h + (-3g) + 1). You could also do something like 3x1(2h + (-3g) + 1). Then draw an equilateral triangle by using a ruler and put 2h + (-3g) + 1 on one side. Then you could put 1 mark through each side of the triangle to show that they are all equal. When you simplify the Perimeter equation, you would get 6 h + -9g + 3 using the distributive property.
