Answer:
2x(4x + 3)
Step-by-step explanation:
8x^2 + 6
So the common terms that can be taken out are x and 2
Hence, it can be written as 2x (4x + 3)
Answer:
%70
Step-by-step explanation:1,000=%100 300+%30 1000 - 300 = 700 so 700 + %70
Draw a diagram to illustrate the problem as shown in the figure below.
Let h the height of the hill. =
At position A, the angle of elevation is 40°, and the horizontal distance to the foot of the hill is x.
By definition,
tan(40°) = h/x h = x tan40 = 0.8391x
(1)
At position B, Joe is (x - 450) ft from the foot of the hill. His angle of elevation is
40 + 18 = 58°.
By definition, tan(58°) = h/(x - 450)
h = (x - 450) tan(58°) = 1.6003(x-450)
h = 1.6003x - 720.135 (2)
Equate (1) and (2).
1.6003x - 720.135 = 0.8391x 0.7612x = 720.135
x = 946.0523
From (1), obtain
h = 0.8391*946.0523 = 793.8 ft
Answer: The height of the hill is approximately 794 ft (nearest integer)
Answer:
Square
Step-by-step explanation:
It has four coordinates which means four vertices which is four sides. Can also be a rectangle or parallelogram.
