How do i find the surface area of a pyramid

Select a graph that have an equation with a < 0

Given abcd ac=38 and ae=3x+4 find the value of x

Type the correct answer in the box. consider the system of linear equations below. rewrite one of the two equations above in the form ax + by = c, where a, b, and c are constants, so that the sum of the new equation and the unchanged equation from the original system results in an equation in one variable.
