So if 0.4x10=4, That means that 4. Is 4/10 of 10.
Answer:
(5x+6)(2x+5)-(2x+4)(x+8) simplified is 8x^2+17x-2
Step-by-step explanation:
The length of an arc subtended by a central angle is proportional to the circle's circumference. If the given central angle has measure and the circle has radius , then the arc has length such that
where is given in radians. Then
If is given in degrees, then
