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 answer is B lm 100% sure
Step-by-step explanation:
Commutative means a + b = b + a
So, 4x + 3 = 3 + x
Associative means a + (b + c) = (a + b) + c
So, 6 + (9 + 7) = (6 + 9) + 7
Distributive means expand the bracket a * (b + c) = a*b + a*c
So, (4x + 3y + 2z) * 7 = 4x*7 + 3y*7 + 2z*7
Commutative is a + b = b + a
So, 15a + 15b = 15b + 15a
