9r because 4+9 is 13+7 is 20-11 is 9
Step-by-step explanation:
sin(s+t) = sin(s)+cos(t) which results
(sin(s)×cos(t))/(cos(s)cos(t)) + (cos(s)×sin(t))/(cos(s)cos(t))
knowing that tan=sin/cos and that cos/cos=1 and sin/sin=1
resulting tan s ×1 + tan t × 1 = tan s + tan t
Jennifer had $4 left. 1/5 of 30 is 6, 1/6 of 30 is 5 and 1/2 of it is 15. Add it together and you get 26. 30-26 is 4

4(3+14c−12d)
=(4)(3+14c+−12d)
=(4)(3)+(4)(14c)+(4)(−12d)
=12+c−2d
=c−2d+12
