Area = (39x18)/2 =351
answer = 351 m^2
Answer:
1
Step-by-step explanation:
= 
= 
= 0.7, rounded to the nearest ones is 1.
To calculate the IQR, we need the radian, which is the middle number of each column, namely (86,82) for each exam.
Above the middle number, we have 5 values. The middle value (of the upper part) is Q3, which is on the third line, or (92,85).
Below the middle number, we also have 5 values. The middle (of the lower half) is Q1, which is on the 9th line (80,78)
The IQR is the difference between Q3 and Q1, namely
(92-80, 85-78) = (12, 7)
Since 12>7, we conclude that the IQR of the mid-term is higher than the final.
Octahedron has 8 faces, icosahedron has 20 faces. Therefore the answer is dodecahedron, it has 12 faces.
Answer
x - 1 + 6x^2
Step-by-step explanation:
Write al the sides together: 2x + 5 + x^2 - 6 + 4x^2 + 2x + x^2 - 3x
Then organize the terms: 2x + 2x - 3x + 5 - 6 + x^2 + x^2 + 4x^2
Simplify: 2x + 2x - 3x + 5 - 6 + x^2 + x^2 + 4x^2
2x + 2x -3x = 4x - 3x = 1x or x
x + 5 - 6 + x^2 + x^2 + 4x^2
5 - 6 = -1
x - 1 + x^2 + x^2 + 4x^2
x^2 + x^2 + 4x^2 = 2x^2 + 4x^2 = 6x^2
x - 1 + 6x^2
