The base edge of an oblique square pyramid is represented as x cm. if the height is 9 cm, what is the volume of the pyramid in terms of x?

3x2 cm3
9x2 cm3
3x cm3
x cm

Me write an equation for the interior angles of this triangle that uses the triangle sum theorem

What is the answer to this question? i'm a bit stumped. also how do i do it? 5(x - 4) = 2(x + 5)

The edge of a cube was found to be 30 cm with a possible error in measurement of 0.4 cm. use differentials to estimate the maximum possible error, relative error, and percentage error in computing the volume of the cube and the surface area of the cube. (round your answers to four decimal places.) (a) the volume of the cube maximum possible error cm3 relative error percentage error % (b) the surface area of the cube maximum possible error cm2 relative error percentage error %
