Answer:
median
Step-by-step explanation:
Step-by-step explanation:
x² + 2x - 5 = 0
that is the same as
x² + 2x + 1 = 6
(x + 1)² = 6
x + 1 = ±sqrt(6)
x = -1 ± sqrt(6)
x1 = -1 + sqrt(6)
x2 = -1 - sqrt(6)
n² - 20n + 2 = 4
this is the same as
(n - 10)² = 102
n - 10 = ±sqrt(102)
n = 10 ± sqrt(102)
n1 = 10 + sqrt(102)
n2 = 10 - sqrt(102)
Answer:
216 meters
Step-by-step explanation:
make a 4 square box. put the numbers 10 & 2 on top an 8 & 10 on the side.then multiply...
8 * 10 = 80
8 * 2 = 16
10 * 10 = 100
&
10 * 2 = 20
then add all the numbers together.... 80+16+100+20 = 216 meters
the end. Can u mark me the brainliest when u get the chance? thnxs
