Answer:
A circle is 360° all the way around; therefore, if you divide an arc's degree measure by 360°, you find the fraction of the circle's circumference that the arc makes up. Then, if you multiply the length all the way around the circle (the circle's circumference) by that fraction, you get the length along the arc
Answer:
a^2 - b^2 = (a+b)(a-b) where a = X and b = 6
(X+6)(X-6)

Step-by-step explanation:
Answer:
y= -5/3 x - 6
Step-by-step explanation:
3x-5y=20
-5y=20-3x
y= (3/5)x - 5
3/5 is the slope
a perpendicular line's slope is the opposite reciprocal
-5/3 = m
y-y1=m(x-x1)
(-6, 4) = (x1, y1)
plug in the values
y-4= -(5/3) (x+6)
y-4= -5/3 x - 10
y= -5/3 x - 6
Answer:
Add 12 and 15 to their X value.
Step-by-step explanation:
X = 28, but they could check by adding 12 and 15 to see if it adds to 55.
