Equation shows identity property of multiplication is (a + bi) × 1 = (a + bi)
The correct option is (d)
The identity property of multiplication says that the product of 1 and any number is that number.
We know, Identity property of multiplication states that
"the product of 1 and any number is that given number".
We know that every complex number have two parts one is real and other is imaginary.
If a is real number and b is imaginary part then by definition
(a + bi) × 1 = (a + bi).
1. Uses Distributive Property of Multiplication.
2. Zero product property.
3. Commutative property of multiplication
4. Identity property of multiplication.
Hence, equation shows identity property of multiplication is (a + bi) × 1 = (a + bi)

Which statement best describes the two expressions?
A. Both are rational.
B. Both are irrational.
C. A is rational, but B is irrational.
D. A is irrational, but B is rational.
Answer:
The answer is 12x-15
Step-by-step explanation:
This is a simplification question, so
5(3x-2) using distributive property makes it (15x - 10)
-(3x+5) negating 3x+5 gives -3x-5
so 15x-10-3x-5 = 12x-15
Hope this helps!
