Answer:9a
Step-by-step explanation:
9ax^2+9ax+9a
9a(x^2+x+1)
Therefore the greatest common factor is 9a
The answer to the problem it 54. because 378 divided by 7 =54
Answer:
16. A
17. D
Step-by-step explanation:
16. By saying that a line intersects one plane and then another, you are saying that a line is existing on two planes. This is a direct contradiction to the statement.
17. The triangle is equilateral because syllogism is basically connecting the dots. If the angles in the triangle are all equal, it has all equal sides, and if it has all equal sides, then it is equilateral, therefore, it is D, not C.
Let and be the respective radii of balloons A and B. If the fixed total volume is V, then
and knowing and at the start, we have V = 6916π/3 cm³. Then when , the radius of the other sphere is .
Differentiating both sides with respect to time t gives a relation between the rates of change of the radii:
We're given the whole time. At the moment , the radius of balloon B is changing at a rate of
