Need worth 15 points which equation would best solve the following problem? the height of a triangle is 4 m less than its base. the area of the triangle is 48 m2. find the length of the base. a. 48 = x(x-4) b. 48 = x^2-4 c. 48 = 1/29(x)(x-4) d. 48 = 1/2(x^2-4)

Suppose that the price p, in dollars, and the number of sales, x, of a certain item follow the equation 4 p plus 4 x plus 2 pxequals56. suppose also that p and x are both functions of time, measured in days. find the rate at which x is changing when xequals2, pequals6, and startfraction dp over dt endfraction equals1.5.
