The second one. is it right?
To simplify the expression we shall have:
-5/(x-3)--4/(x+2)
=-5/(x-3)+4/(x+2)
putting the fraction under the same denominator
[-5(x+2)+4(x-3)]/[(x-3)(x+2)]
=[-5x-10+4x-12]/[(x-3)(x+2)]
=[-x-22]/[(x-3)(x+2)]
Answer:
[-x-22]/[(x-3)(x+2)]

Answer:
172.5
Step-by-step explanation:
Use similar triangles and a proportion.
(tree height)/(tree shadow length) = (your height)/(your shadow length)
x/(270 ft)= (5 ft 9 in.)/(9 ft)
x/(270 ft)= (5 ft + 9/12 ft)/(9 ft)
x/(270 ft)= (5.75 ft)/(9 ft)
9x = 270 * 5.75 ft
x = 30 * 5.75 ft
x = 172.5 ft
