Answer:
d=√((x_2-x_1)²+(y_2-y_1)²)
Step-by-step explanation:
use your brain and fill in the variables
Answer:
x=30. y=60
Step-by-step explanation:
DG is a straight segment so it sums to 180 degrees. ECG is a right angle so 90 degrees. The rest is described as 2x and x. So 3x=90 degrees. x=30. Eh is also a straight segment. since we know x, we know that ECD is 60 degrees. So y+y=120 degrees. 2y=120. y=60.
1 pound = 16 oz
Her books weigh 9 pounds or (9)(16)= 144 oz
Math Textbook= 40 oz
Biology textbook= 3 pounds or (3)(16)= 48 oz
Total weight of books - math textbook - biology textbook = science textbook
144-40-48 = 56oz
science textbook = 56oz
7x - (25x^2 + 12x) = 7x - 25x^2 - 12x = -25x^2 - 5x
Omg what level are you that is so hard
