Answer:
x-5=sqrt(2x+5)
then square both sides
x2-10x+25=2x+5
x2-8x+20=0
rest is trivial
Step-by-step explanation:
Answer: 6.67 feet (check to see if you made a typo)
Step-by-step explanation:
if the scale factor is ten than we multiply 8 by 10
8 * 10 = 80
important to remember this is 80 INCHES not 80 FEET
to convert 80 inches into feet, we divide by 12 because there are 12 inches in a foot
80/12 = 6.67 feet
check to make sure that the first option is actually 6.67 inches because it would make more sense for it to be in feet
Answer:
Explained
Step-by-step explanation:
The trunk of a tree grows in two different ways, first in height and second in diameter.Usually tree grows one ring per year in diameter. So, counting the number of rings we can determine the age of a tree. Both height and diameter growth does not occur at the same rate. Tree grows more in height than in their diameter. Mature trees usually grows 1 inch in diameter every year.
Water oak gains 24 inches in height every year and 1.5 inch growth in diameter annually, meaning if we divide 1.5 inches by 12 months we gets 0.125 inches growth monthly. So a water oak tree needs only 8 months to grow 1 inch in diameter.
