This is false. The f(3x) means you are multiplying the input 'x' by 3 before plugging into the equation. 3f(x) means you are going to multiply your answer (output) by 3 after you've plugged the input value in and gotten the output.
Since we know a square has 4 equal sides and is equal to to exact right triangles. USing the formula for Perimeter l+l+w+w=P or 2L+2W=P 56cm÷4=14 so now we have (2)14+(2)14=P P=14cm^2 The slant length on a triangle is equal to L Slant lenght=14
