Answer:
179 animals were still at the river
Step-by-step explanation:
There were 632 animals at the river.
A herd of 187 elephants and 266 zebras left the river area.
This means that 187 + 266 = 453 animals left the river area.
Remaining:
632 - 453 = 179
hello :
h(x) = x² – 5x + 7
h(-2) = (-2)² – 5(-2) + 7 =4+10+7 =21
h(-5) = (-5)² – 5(-5) + 7= 25+25+7 =57
h(-8) = (-8)² – 5(-8) + 7 = 64+40+7=111
21
Its 61
