Using the formula a(b+c) = ab + ac, then 7(2x-6) = 14x - 42. The answer is D.
<span>The
value of the determinant of a 2x2 matrix is the product of the top-left
and bottom-right terms minus the product of the top-right and
bottom-left terms.
The value of the determinant of a 2x2 matrix is the product of the top-left and bottom-right terms minus the product of the top-right and bottom-left terms.
= [ (1)(-3)] - [ (7)(0) ]
= -3 - 0
= -3
Therefore, the determinant is -3.

Answer:
32
Step-by-step explanation:
Area = a+b/2 * h
6+10/2= 8
8*4 = 32
Addition/Subtraction and. Multiplication/ Division ... So checking one operation with its opposite is a good way to help verify your answer.
