Answer: The Distributive Property
Aiko didn't seem to realize that rewriting it like that would cause the expression to have a different solution. She should study her math.

Answer:

Given the expression: (4+5i)+(-3+7i)

Aiko rewrites the equation by factoring out the i from the expression and this wrote it as,

(-3+7)i+(4+5)i

but this is wrong because i is an imaginary number which is with a number 5 and 7.

Therefore,  Aiko cannot factor out the i because it is not present in both numbers -3 and 4

She could rewrote it as

(4-3)+i(5+7)

So, she incorrectly used the distributive property by combining the real number and the coefficient of the imaginary part.

TV=3x-24 and VX=2x+1. What is the value of VX?<br> 1. 25<br> 2. 99<br> 3. 5<br> 4. 51
Maslowich
ΔTXV is an <span>isosceles triangle because ∡T = ∡X therefore TV = VX.

3x - 24 = 2x + 1    |subtract 2x from both sides

x - 24 = 1    |add 24 to both sides

x = 25
