Answer:
The tree is 15 feet tall
Step-by-step explanation:
6 feet tall - 10 feet shadow
x feet tall - 25 feet shadow
x=(25*6)/10=15 feet
Two sides are 34 and 14.
The third side can't be longer than (34 + 14) = 48, because the 34 and the 14
together could not reach from one end of it to the other.
The third side also can't be shorter than 20, because the 20 and the 14 together
could not reach from one end of the 34 to the other.
So 18 doesn't work. (18 + 14) = 32 ... they couldn't cover the 34 .
Answer:
Domain: all real numbers
Range: less than/equal to -2
first multiply the outside numbers by both the numbers in the ()
10xg=10g 10x5=50 2xg=2g 2x9=18
then combine like terms
10g+50=2g+18
8g=32
then divide
g=4
