Answer:

<h2><u><em>x = 1</em></u></h2>

Step-by-step explanation:

3x + 2 = (2x + 13)/3

9x + 6 = 2x + 13

9x - 2x = 13 - 6

7x = 7

x = 7 : 7

x = 1

100 points PLEASE ANSWER ASAP thank you so much
Fudgin [204]

Answer:

\textsf{Apply the Perfect Square Formula}\quad (a + b)^2 = a^2 + 2ab + b^2:

\implies (a+bi)^2=a^2+2abi+(bi)^2

\textsf{Apply exponent rule} \quad (a\cdot b)^c=a^cb^c:

\implies a^2+2abi+b^2i^2

i=\sqrt{-1} \implies i^2=-1

\textsf{Apply imaginary number rule} \quad i^2=-1:

\implies a^2+2abi+b^2(-1)

\implies a^2+2abi-b^2

\textsf{Collect the real parts:}

\implies a^2-b^2+2abi

\textsf{Factor the real parts by applying the Difference of Two Squares Formula}\\x^2-y^2=(x+y)(x-y) :

\implies (a+b)(a-b)+2abi
