Answer:
-2x - 5 (lesser than or equal to) 15
If the length of the ladder is x then 12/x=cos70, so x=12/cos70=35’ approx, answer c.
-6 is the answer that you want
terms is x first then terms in y and constant after the equals
Its C
Area of the shaded region=area of the greater rectangle- area of the inner rectangle.
Area of a rectangle=length x width.
Area of the greater rectangle=(8x-1)(6x)
area of the inner rectangle=(5x+3)(2x)
Area of the shaded region=(8x-1)(6x)-(5x+3)(2x)
=48x²-6x-(10x²+6x)
=48x²-6x-10x²-6x
=38x²-12x
Answer: the area of the shaded region would be: 38x²-12x
