Neither of them do,
The first one gives you:
1=-19
The second one gives you:
2=9
Neither of which are true.
Hope this helps :)
The answer is 32. All you have to do is multiply 8 and 4 to get 32, which if you divide by 8 equals 4.
It is possible to see that the angle DCB is a right angle. It is also seen that sides CD and CB are congruent. So, the measure of angles CDB and CBD is the same. Since the sum of the three angles must be equal to 180°, the angle CDB must be equal to 45°.
∠CDB + ∠CBD + ∠DCB = 180°
∠CDB + ∠CBD + 90° = 180° (Replacing the value of angle DCB)
∠CDB + ∠CBD = 180° - 90° (Subtracting 90° on both sides of the equation)
∠CDB + ∠CBD = 90° (Subtracting)
2*∠CDB = 90° (Since ∠CDB = ∠CBD )
∠CDB = 90°/2 (Dividing by 2 on both sides of the equation)
∠CDB = 45°
D is the answer, Since D is division and polynomials are not closed under division.
Answer:
The definition of a vector that you learn in linear algebra tells you everything you need to know about what a vector is in any setting. A vector is simply an element of a vector space, period. ... So, to say that a vector is a column of numbers, or a geometric object with magnitude and direction, is incorrect
