Answer:
After simplify answer will be :
Step-by-step explanation:
Given data:

Now,

Final answer would be :
-2x + 11 + 6x
put the x’s together
-2x + 6x
= 4x
put them together again
4x + 11
bring 11 on other side with (-)
4x = -11
divide by 4
x = -11/4
answer
x = -11/4 or -2.75
Start here: A = 18 ft^2 = L * W. Next, L = 2W.
Merging these 2 formulas lets us eliminate L:
18 ft^2 = (2W) * (W) = 2W^2.
So W^2 = 9 ft^2, and W=3 ft. Please use L = 2W (from above) to calculate L.
Answer:
Therefore the height of the tower is 101.79 m.
Step-by-step explanation:
The ratio of the height of an object to the shadow of the object is always constant at certain time.


Given that,the length of the pole is 3.5 m and it casts a shadow that is 1.47 m long.
The length of shadow that castes by a tower is 42.75 m long.
Here h₁= 3.5 m, s₁=1.47 m, h₂= ? and s₂=42.75 m

⇒3.5 ×42.75 = h₂× 1.47

⇒h₂ = 101.79 m (approx)
Therefore the height of the tower is 101.79 m.
Answer:
It will describe the sum of the numbers scanned.
As we can see whatever you scan or take input it will be added to s without any condition. So at the end, sum of all scanned number will be save in variable s
