Answer:
35,66
Step-by-step explanation:
Perimeter:
(5.5+12)*2
=17.5*2
=35m
Area:
5.5*12
=66 sq. metres
Answer:
Step by Step:
x-2y=4
+2y +2y
x=-2y+4
x-2y=4
-4 -4
x-2y-4=0
+2y +2y
x-4=2y
Divid by 2
1/2x-2= y
x=-2y+4
x=-2(1/2x-2)+4
x=-x+4+4
x=-x+8
+x +x
2x= 8
x=4
y=1/2x-2
y=1/2(4)-2
y=2-2
y=0

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
Answer:
D. 30 - 6n + 3 × 8 for n = 3.5
Step-by-step explanation:
Replace n by given value
30 - 6×(3.5) + 3 × 8 (Do the multiplying first then add and subtract)
➡
30 - 21 + 24 = 33
11+2x=2+5x
11=2+3x
9=3x
3=x
