Answer:
12
Step-by-step explanation:
The area of a parallelogram is equal to its base times its height. Segment DX is a height relative to the base BC, so (area of ABCD) = BC times DX,

Answer:
B
Step-by-step explanation:
The "value" of a function is the y-value.
Since we want negative y values, we look at "WHERE" the function is "UNDER" the y-axis.
Looking closely, it looks that function (the dip) is from x = -1 to x = 3
Hence, the function is negative at the interval -1 ≤ x ≤ 3
B is correct.
