What is the value of the expression 6 + 4(8-5)

Name each raycalculation tip: in ray "ab", a is the endpoint of the ray.

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?

If x = -2, then x 2-7x+10 equals a. 0 b.20 c.28
