i need with at least these questions.

1) multiply and simplify.

(3 + i)(4 + 2i) a) 7 + 3i b) 7 − 10i c) 10 + 10i d) 10 − 10i

2) what is the remainder r when the polynomial p(x) is divided by (x + 5)? is (x + 5) a factor of p(x)? p(x) = x3 - 5x2 + 2x - 10 a) -16i b) -16 c) -4i d) 4i

3) use the imaginary number "i" to rewrite the expression: the negative square root of -16 a) -16i b) -16 c) -4i d) 4i

4) use the imaginary number "i" to rewrite the expression as a complex number: square root with 100 + square root with -81 a) 9 i b) 10 + 9i c) 10 - 9i d) 19i

5) convert the expression cube root of 2 to exponential form. a) 21/3 b) 23 c) 32 d) 31/2
