Answer:
Plug the variables into the equation = 7(7)-(3(2) - (1)) = 44
Step-by-step explanation:
Use distrubutive property <em>a(b + c) = ab + ac</em>
6(5r - 4) - 2(r - 7s - 3)
= (6)(5r) + (6)(-4) + (-2)(r) + (-2)(-7s) + (-2)(-3)
= 30r - 24 - 2r + 14s + 6
= (30r - 2r) + 14s + (-24 + 6)
Length of arc = central angle made by the arc/360° × 2πr
