Answer:
width = 5 m
Step-by-step explanation:
let the width of the room be w then the length = 2w + 5 ( that is 5 more than twice its width )
perimeter is the sum of the sides
for a rectangular room the perimeter is calculated as
perimeter = 2 ( length + width ) = 2(2w + 5 + w) = 2(3w + 5)
given the perimeter is 40 m , then equating
2(3w + 5) = 40 ( divide both sides by 2 )
3w + 5 = 20 ( subtract 5 from both sides )
3w = 15 ( divide both sides by 3 )
w = 5
that is the width of the room is 5 m

The solution of expression after multiplying is,
⇒ 25n² + 5n - 30
We have to given that,
To multiplying polynomials is,
⇒ (5n + 6) (5n - 5)
Now, We can multiply as,
⇒ (5n + 6) (5n - 5)
⇒ 5n × 5n + 5n × - 5 + 6 × 5n + 6 × - 5
⇒ 25n² - 25n + 30n - 30
⇒ 25n² + 5n - 30
Therefore, The solution is,
⇒ 25n² + 5n - 30

Let y= side 2=unknown
Let z= side 3=unknown
Since it is an isosceles triangle, two sides are equal, which happen to be y and z
Hence y=z
Perimeter of a triangle = Sum of all three sides
= x+y+z
51=19+2y [since we know x=19 and y=z, we know the perimeter is 51]
Solve now
32=2y
16=y
Since y=z
z= 16
Hence the unknown side's length is 16m

20,000 = 15,000 (1.072)^t
Divide each side by 15,000 : 4/3 = (1.072)^t
Take the log of each side: log(4/3) = t log(1.072)
Divide each side by log(1.072): t = log(4/3) / log(1.072)
0.12494 / 0.03019 = 4.138 (rounded)
