Answer:
D
Step-by-step explanation:
there are 3 ft in a yard, so to find how many yards you multiply 3 time 12, which equals 36.
"3 less than twice 'x' " . . . . that's (2x - 3)
" 2 more than the quantity (3 x) " . . . . . that's (3x + 2)
Their product is
(2x - 3) (3x + 2) .
If you want to expand it to a single expression, perform the multiplication,
and you have
6x² - 5x - 6 .
The answer is D.

A^2 + b^2 = c^2
