When multiplied, what is the simplified form of (4 – 3i)(7 +11i)? Write the answer in standard form, a + bi where a and b are real numbers.
O 11 +8i
0 -5 + 23i
O 61 +232
O 61 - 651

65+23i

Step-by-step explanation:

(4-3i)(7-11i)

28+44i-21i-32i^2 *i^2= -1

28+44i-21i-33(-1)

65+23i

15

step-by-step explanation:

we are given the following expression and we are to solve it and find the product:

-13 × (-5)

solving the given expression in the standard order of solving a mathematical expression, beginning with the opening of brackets and then multiplying the terms and changing their signs.

-3 × -5 = 15 (answer is positive because when negative is multiplied with negative, it gives a positive answer)
