Answer:
Hominids
*Appeared 3 to 4 million years ago in souther and eastern Africa.
*Humanlike creatures called primates
*Mary and Louis Leakey excavated hominid fossils in the Great Rift Valley
*"Lucy," and Australopithecine fossil, found in 1974.
*Three major differences from earlier primates: bipedalism (gives ability to walk upright), a sizable brain (enables abstract thought and fine motor control), and a larynx (allows for complex speech)
*Thought-processing ability led to alteration of the natural environment to suit human needs
I believe it was negative. When the colonist arrived from Spain to Latin America, many Natives died and were killed, and I do not think that is such a great thing. I believe that the discovery of Latin America did contribute to many new discoveries such as foods and the columbian exchange that changed the diets of Europeans which made people more healthy and live longer. However, all these discoveries of animals, and foods lead to famine, death, and disease among the Native Americans hence also leading to slavery due to the many deaths of Natives, the colonist needed workers so, slavery then happened.
Answer: 84
Steps:
1. Find distance between (-8,-6) and (4,-6) using distance formula:
√ (4 - (-8))^2 + ((-6) - (-6))^2
√ (12)^2 + (0)^2
√ 144 + 0
√ 144
12
2. Find distance between (1,2) and (8,2) using distance formula:
√ (8-1)^2 + (2-2)^2
√ (7)^2 + (0)^2
√ 49 + 0
√ 49
7
3. Multiply found values to find area
A = l x w
A = 12 x 7
A = 84
