Substitute the given values into the given formula and solve for the unknown variable. If necessary, round to one decimal place. S=4LW +2WH; S=120, L = 9, W=3. (Surface area of a special rectangular box)
H=

for this case we must apply distributive property to the following expression:

the distributive property states that:

then, when applying the property we have to multiply the -2 for each term within the parenthesis:

step-by-step explanation:

assume that you have 3 different side lengths.   apply the pythagorean theorem here:   square each of the two shortest sides; call them a and b, so that their squares are a² and b².   also square the longest side, calling the result c².

now, if a² + b² = c² is true, the triangle is a right triangle; otherwise it is not a right triangle.
