Nathan has a sculpture in the shape of a pyramid. the height of the sculpture is 3 centimeters less than the side length, x, of its square base. nathan uses the formula for the volume of a pyramid to determine the dimensions of the sculpture: here, a is the side length of the pyramid’s square base and h is its height. if 162 cubic centimeters of clay were used to make the sculpture, the equation x3 + x2 + = 0 can be used to find that the length of the sculpture’s base is centimeters.

c.   x=2.4cm

step-by-step explanation:

similar triangles are triangles which have the same shape but not the same size. this means their angle measures are equal but their side lengths are not instead they are proportional. to solve, we will set up a proportion and solve.

a proportion is two equal ratios set equal to each other. we form the ratios by finding corresponding sides (sides which match to each other on both triangles by their position). out ratios will be one side of the small triangle over the corresponding side on the big triangle as shown below:

.

to solve the proportion, we'll cross multiply by multiplying numerator with denominator across the equal sign.
