A student multiplies (4+5i) (3-2i) incorrectly and obtains 12-10i what is the students mistakes

1. In the multiplication of the imaginary parts, the student forgot to square of i. OR

2. The student has only multiplied the real parts and the imaginary parts.

Correct value .

Step-by-step explanation:

The given expression is

A student multiplies (4+5i) (3-2i) incorrectly and obtains 12-10i.

Student's mistake can be either 1 or second:

1. In the multiplication of the imaginary parts, the student forgot to square of i.

2. The student has only multiplied the real parts and the imaginary parts.

Which is not correct. The correct steps are shown below.

Using distributive property, we get

Therefore, the correct value of is .

i believe it is c.y = 9x

rise over run. 9 units up over 1 unit right or 9/1

3-4

step-by-step explanation:

the answer is 3-4 because both 45 and 60 has a multiple of 15.

45/3=15

60/4=15

therefore the odds against selecting a red is 4-3
