Given:
radius = 30 inches
Circumference of a circle = 2 * π * r
C = 2 * 3.14 * 30 inches
C = 188.40 inches
Answer is Choice B. 188.4 inches.
Answer:
-3x^2+2xy-4y^2
Step-by-step explanation:
(x^2+xy-3y^2)-(4x^2-xy+y^2)
x^2-4x^2+xy-(-xy)-3y^2-y^2
-3x^2+xy+xy-4y^2
-3x^2+2xy-4y^2
Since you are subtracting 2 logs, you write the single log as a quotient.
Step 1) y=16-x2. Swap the sides so that all terms of the variables are on the left side. Step 2) 16-x_{2}=y. Subtract 16 from both sides. Step 3) -x_{2}=y-16 Divide the two sides by -1. Step 4). \frac{-x_{2}}{-1}=\frac{y-16}{-1} Dividing by -1 undoes the multiplication by -1. Step 5). x_{2}=\frac{y-16}{-1} Step 6) dived y-16 by -1 And the final answer = x_{2}=16-y
