Answer:
Shaded = 12 cm^2 Unshaded = 1.96 cm^2
Step-by-step explanation:
<u>This is really an </u><u>impossibly</u><u> out- of- scale drawing :</u>
<u> (assuming if it </u><u>LOOKS</u><u> like a right angle it </u><u>IS</u><u> a right angle ) </u>
Other side of large <u>rectangle</u> (via pythagorean theorem):
= sqrt (8^2 - 5^2) = sqrt 39
Large <u>rectangle</u> area = 5 x sqrt39 = 13.96 cm^2
Small shaded rectangle = 4 x 3 = 12 cm^2
UNshaded area = large area - shaded area = 13.96 - 12 cm^2 = 1.96 cm^2
Common factors for the various terms include -1, 7, y. Factoring out the product of those gives ...
... -7y(3xz +4x +5z) . . . . . . matches selection B)
