If 3 boxes weigh 0.53 pounds each, what is the total weight?

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?

Evaluate the expression. (9 + 5)(3 + 2)0

Math it's appreciated. (picture provided)
