You need to isolate the variable (x) by performing the opposite operation.

Since 3 is multiplied by x, the opposite would be dividing by 3. What you do on one side you do on the other side, so you would need to divide -12 by 3 as well.

In your case, the answer is B

Given that a room is shaped like a golden rectangle, and the length is 29 ft with the ratio of  golden rectangle being (1+√5):2, thus the width of the room will be:
ratio of golden triangle=(length if the room)/(width of the room)
let the width be x
thus plugging the values in the expression we get:
29/x=(1+√5)/2
solving for x we get:
x/29=2/(1+√5)
thus
x=(29×2)/(1+√5)
answer is:
x=58/(1+√5)
or
 byrationalizing the denominator by multiplying both the numerator and the denominator by (1-√5)
58/(1+√5)×(1-√5)/(1-√5)
=[58(1-√5)]/1-5
=(58√5-58)/4

The inside side is congruent by reflective property

We have 3 congruent sides, so the triangle is congruent by SSS
