A company ships gasoline in tanks. Together, 3 tanks can hold 84 tons of gasoline. How many tanks does the company need to ship 420 tons of gasoline?

the formula of a slope:

we have the points (-2, 7) and (2, 3). substitute:

1. 16.64

a^2+b^2=c^2

pr^2=pq^2+qr^2

pr^2=14^2+ 9^2

pr^2=196+81

pr= sqr root of 277

16.64

2. 11.31

c^2-a^2=b^2

18^2- 14^2=b^2

b^2=324-196

b=sqr root of 126

b=11.31

hope it ! (btw im in connections academy to, good luck! )
