Answer:
17/21
Step-by-step explanation:
1/7 + 2/3
1/7 = 3/21
2/3 = 14/21
then:
1/7 + 2/3 = 3/21 + 14/21
= (3+14)/21
= 17/21
1/7+2/3
3+14/21
THAT THE TRIANGLE ACCORDING TO QUESTION AND I THINK SO OPTION A IS RIGHT 95%
300,350,400,450
the formula for any n term is:
tn=a1+(n-1)d
t1= 300+(1-1)d=300
t2= 300+(2-1)50= 350
t3= 300+(3-1)50= 400
t4= 300+(4-1)50 = 450
and so on...
angleD=(7b+1)angle E=(2b+1)and angle F=(b+8)
