Means multiply 2 3/2×6 ok
Volume = Area of triangle x length
Area of triangle = 1/2 x base x height
Area of triangle = 1/2 x 5 x 4
Area of triangle = 10
Volume = area of triangle x length
Volume = 10 x 12
Volume = 120 cm^3
The answer is option B. In the distributive property you need to multiply the constant that is outside of the parenthesis, with the terms that are inside :)
I agree it is one and I used this calculator called MathPapa that can help with algebra you should try it. It is free.
