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

A rectangle garden has a length of 12 feet. you need 36 feet of fencing to enclose the garden. what is the width of the garden ?

iren [92.7K]

Let us suppose the width is x feet

the length is given 12 feet

Perimeter of teh garden = 2( Length + width )= 2( 12+ x)

Fencing required = perimeter of garden

36 = 2( 12+x)

36 = 2*12 + 2x

36 = 24 + 2x

36-24 = 2x

12 = 2x

12/2 = x

6 = x

Width = x feet = 6 feet .Answer .
