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)

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
