Provide a counterexample:
Jobisdone [24]

Answer:

a=2 \quad \text{and} \quad b=-2

Step-by-step explanation:

Take a=2 \quad \text{and} \quad b=-2, note that

2=(-1)\cdot(-2)

hence b divides a. On the other hand, we have that

-2=(-1)\cdot2

which tells us that a divides b. Moreover, a=2 \neq -2=b.

You are hiking along the California coast and wonder about the height of a particular Giant Redwood tree. You are 5
yulyashka [42]

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
