Each surface has area = 3*3 = 9 m^2
As there are 6 surfaces te total area = 6*9 = 54 m^2 answer.
Hi!
<u>Positive</u> <u>discriminants</u> will give you <u><em>two</em></u> <u>solutions</u>.
<u>Discriminants</u> <u>equal</u> <u>to</u> <u>zero</u> will give you <u><em>one</em></u> <u>solution</u>.
<u>Negative</u> <u>discriminants</u> will give you <u><em>no</em></u> <u>solutions</u>.
In a graph, the number of solutions is where the graph crosses the x-axis.
In the first graph, we can see it intersects the graph at two points: (2, 0) and (6, 0). Since there are two solutions it is a positive discriminant.
In the second graph, we can see it intersects at one point: the origin, or (0, 0). Since there is one solution it is a discriminant equal to zero.
In the third graph, we can see it doesn't intersect; it is above the x-axis. Since there are no solutions it is a negative discriminant.

Answer: A. W-0.04w
F. 0.96w
Step-by-step explanation:
Let the original plot of land that the farmer owns be w.
Since he sold some part of the land which decreased his total acreage by 4%, the expression for the new acreage will be for 4% of the original plot of land to be deducted from the original land. This will be:
= w - (4% × w).
= w - (4/100 × w)
= w - (0.04 × w)
= w - 0.04w
= 0.96w
Therefore, the correct options are A and F.
