1.Simplify (-4 + 5i) + 2(1 + 3i) Enter your answer in the form a + bi 2. Calculate |-3 + 4i|. (Points : 3) 5 2 -5 -2 3.Convert 4(cos(240degree) + isin(240degrees))into rectangular form. (-2,-2,squareroot3) (2,squareroot3,-2) (-4,4,squareroot3) (4,4,squareroot2)
(-4 + 5i) + 2(1 + 3i) = -4 + 5i + 2 + 6i = -2 + 11i |-3 + 4i| =
