1. Select all values of x that are solutions to the equation: -2(x + 4)(3x - 18) = 0A) -6B) -4C) -2D) OE) 2F) 4G) 6

navik [9.2K]

$\begin{gathered} -2(x+4)(3x-18)=0 \\ \text{There are two factors here which are} \\ -2(x+4)\text{ and} \\ (3x-18) \\ \text{This means, either} \\ 2(x+4)=0 \\ 2x+8=0 \\ 2x=-8 \\ \text{Divide both sides by 2} \\ x=-4 \\ OR \\ 3x-18=0 \\ 3x=18 \\ \text{Divide both sides by 3} \\ x=6 \\ \text{Therefore,} \\ x=-4\text{ or} \\ x=6 \end{gathered}$

x = -4 OR x = 6

The correct options are B and G

What’s the answer<br><br><br> 5n-2=n+18

Sauron [17]

5n-2=n+18

Move n to the other side

Sign changes from +n to -n

5n-n-2= n-n+18

5n-n-2= 18

4n-2= 18

Move -2 to the other side

Sign changes from -2 to +2

4n-2+2= 18+2

4n= 18+2

4n= 20

Divide by 4 for both sides

4n/4= 20/4

Answer: n=5
