Distributive vector multiplication
 1) Which expression can be written as 7(c + d)? 7c - 7d 7c + 7d 7c / 7d 7c x 7d

 2) Find the mistake in this problem: 3(x + 2) = 3x + 2. should have added the 3 and 2 should multiply the 3 and X should have minus the 3 and 2 No problem

 3) Find the mistake in this problem: 5(x + 8) = 5x - 40? No problem should have added the 5 and 40 should have minus the 5 and 40 should have multiply the 5 and 40

 4) What is the area of the parallelogram? b=A*h A=b+h A=b*h A=b*h

 5) Which equation violates the distributive property of vector multiplication ? (A + B) x C = A x C + B x C A x (B + C) = (A x B) + (A x C) A x (B + C) = A x B + A x C (A + B) x C = A x C - B x C

 6) Where distributive property of vector multiplication over addition can be applied? Scalar addition Cross product Vector addition Scalar multiplication

 7) The distributive property of vector multiplication is valid only for scalar multiplication. None of these statement is incomplete. False True

 8) Where the distributive property of vector multiplication can be applied? Vector subtraction Vector cross product Scalar product Scalar multiplication

 9) Which is true about the cross product of two vectors? It is commutative, i.e A x B = B x A It produces a scalar quantity It is used to find the angle between two vectors It is defined only in two-dimensional space

 10) What is the dot product of two vectors Tensor Scalar Vector Matrix
