Answer:
and 
.
Step-by-step explanation:
We have been given a system of equations. We are asked to solve our given system.
From equation (1), we will get:
Upon substituting this value in equation (2), we will get:
Now, we will substitute in equation (1).
Therefore, the point 
is solution for our given equation.
Answer: 4.8 ft
To answer this question you need to know how much shadow: actual height ratio. Flagpole is having 8 ft shadow with 20 ft actual height. The ratio should be= 8 ft: 20 ft= 0.4
Then multiply the ratio with the oak tree shadow. The equation would be:
0.4 x 12 ft= 4.8 ft
Find the area of the square first
Area = Length x Width
Area = 12 x 9
Area = 108
Find the area of the right triangles
Area = 1/2(Length x Base)
Area = 1/2(9 x 2)
Area = 1/2(18)
Area = 9
Since there is 2 triangles multiply by 2
9 x 2 = 18
Now add
108 + 18 = 126
126 is your area
