2x^2+8xy+8y^2
2(x^2+4xy+4y^2)
Answer:
$8.40
Step-by-step explanation:
8.6 plus 8.2 is 16.8 so they had a total of 16.8 ounces. $0.50 per ounce so you need to multiply 16.8 by 0.50 which is 8.40. you can also do 8.6(0.5) plus 8.2(0.5)= 4.3 plus 4.1 = 8.4
From the following figure:
Because the center angle measure 45 degrees, we must rotate 3 times 45 degrees to get point D.
In other words, we must rotate

that is 135 degrees clockwise.
