Answer:

The correct option is 1.

Step-by-step explanation:

It is given than the area of the triangle ABC is 46cm².

Area of a triangle is

$A=\frac{1}{2}\times base\times height$

Base of the triangle is AB and height of the triangle is CD.

$A=\frac{1}{2}\times AB\times CD$

$A=\frac{1}{2}\times AB\times 8$

$A=4\times AB$

The area of the triangle is 46cm².

$46=4\times AB$

$AB=\frac{46}{4}$

$AB=11.5$

Therefore the length of side AB is 11.5 cm. Option 1 is correct.

-4 (x -3) = 20

luda_lava [24]

Where did the 20 go
it just magically disappeared in the equation
-4(x-3)=20
-4x+12=20
move 12 to the other side , making it negative
-4x=20-12
-4x=8
x=-2
