Answer:
Two solutions are found:
n=0 , n= 4 ....
Step-by-step explanation:
n^2-4n = 0
Take common from the given expression:
n(n-4)=0
When a product of two or more terms equals zero, then at least one of the terms must be zero.
We shall now solve each term = 0 separately;
n(n-4)=0
n = 0.
n-4 = 0.
Add 4 at both sides:
n-4+4 = 0+4
n = 4
Therefore two solutions are found:
n=0 , n= 4 ....
The answer for missing angle S is 60°
8+11=19 but if you add 21+19+12+5=57.
Area=width*length. Let width=x ft, then length=3x ft, given the information in the problem. The area of basement=x*3x=768, 3x^2=768, x^2=256, x=16. The width is 16 feet. Therefore, length=3x=3*16=48 feet.
