The area of the triangle shown is represented by A=s(s−9)(s−8)(s−5)−−−−−−−−−−−−−−−−− −√, where s is equal to half the perimeter. What is the height h of the triangle? Round your answer to the nearest hundredth.

Simplify the expression. -2/5(10+15m-20n)

Write a polynomial function f of least degree that has rational coefficients, a leading coefficient of 1, and the given zeros. 3, 4+2i, 1+(sqrt)7 the answer is supposed to be: f(x)=x(^5)-13x(^4)+60x(^3)-82x(^2)-144x+360 what am i doing wrong?

List x1, x2, x3, x4 where xi is the midpoint endpoint of the five equal intervals used to estimate the area under the curve of f(x) between x = 0 and x = 10.
