Marysya12 [62]

Answer:

A) 4*4x-4*3 and 16x-12

B) 12y+15y and 27y

Step-by-step explanation:

For A when you do the distributive property, you get:

4(4x-3)

4*4x-4*3 (which is one of the choices)

16x-12 (which is one of the choices)

For B when you combine like terms, you get:

12y+5y+10y

12y+15y (which is one of the choices)

27y (which is one of the choices)

ASAP WILL MARK BRAINLYEST <br><br>solve these four please!!

I dont know if you wanted the steps but:

x^2-4x-6=0

plug it into the equation:

\frac{-(-4)\sqrt{(-4)^2-4(1)(-6)}}{2(1)}

[tex] \frac{4\sqrt{40}}{2} [/tex]

\frac{4+2\sqrt{10}}{2}    \frac{4-2\sqrt{10}}{2}

x=2+\sqrt{10}

x=2-\sqrt{10}

x^2-4/3x+1/3 x=1 , x= 1/3

2x^2-3x+1=0 x=1 , x=1/2

6x^2+12x=-5

add the 5 to both sides

6x²+12x+5=0 plug the problem into the equation

x=\frac{-12\sqrt{12^{2}-4(6)(5)}}{2(6)}

x=[\frac{-12\sqrt{144-120}}{12}

x=\frac{-12\sqrt{24}}{12}

x=\frac{-12+2\sqrt{6}}{12} x=\frac{-12-2\sqrt{6}}{12}

\frac{-6+2\sqrt{6}}{6} \frac{-6-2\sqrt{6}}{6}
