Answer:
16 feet
Step-by-step explanation:
The shadow is 20/30 = 2/3 the length of the object, so the 6-foot person's shadow will be 4 ft long. It will begin to emerge when the person is 4 feet from the tip of the building's shadow. That distance is ...
20 ft - 4 ft = 16 ft
from the building.
Total of 16 pieces in the chess which foam our sample space.
Total of 2 pieces of bishop.
If you first chose the bishop then probability =2/16=1/8=0.125
If you again chose the bishop without replacement(total sample space left=15 and 1 piece of bishop left) then probability =1/15=0.0666
(3x² + 2xy + 4y²) + (6x² - 5xy + 3y²) + (9y² - 25y²)
Get rid of the parenthesis :)
3x² + 2xy + 4y² + 6x² - 5xy + 3y² + 9y² - 25y²
Add like terms.
(3x² + 6x²) + (2xy - 5xy) + (4y² + 3y² + 9y² - 25y²)
Simplify.
(9x²) + (-3xy) + (-11y²)
Get rid of the parenthesis.
9x² - 3xy - 11y²
