Answer:
4x2−12x+9=0
Step-by-step explanation:
The equation, 2x2+x+3=0, does not have a solution
The equation, x2+5x−3=0, equals -5/2+1/2√37 and -5/2+-1/2√37
The equation, x2−5x+4=0, equal 1 and 4
The equation, 4x2−12x+9=0, equals only 3/2

Tan(40) = .84
.84/1 = x/60
x = 50.4
The height of the tree equals 50.345 rounded to 50.4
Answer:
93.6
Semi circle - 31.81 (rounded)
Step-by-step explanation:
find the area of the triangle which is 1/2 6*5.2 -=15.6
there are 6 triangles so that means it has to be multiplied by 6 - 15.6*6 = 93.6
Use the semi cirlce formula- (pi*r^2)/2
In this situation that is (pi*4.5^2 )/2 = 31.81 (rounded)
Area = length x width
the "big" rectangle: length = 15, width = 14
the blue rectangle is: length = 15 - 4, width = 14 - 6
Area of blue rectangle = (15 - 4)(14 - 6)
