For the functions latex: u\left(t\right)=6t-7u ( t ) = 6 t − 7 and latex: s\left(t\right)=t^2-4s ( t ) = t 2 − 4, what is latex: s\left(u\left(2\right)\right)s ( u ( 2 ) )?

  21

Step-by-step explanation:

Put the numbers where the letters are and evaluate.

  s(u(2)) = s(6·2 -7) = s(5) = 5² -4 = 21

16

step-by-step explanation:

2 x 40 = 80

80/5

= 16
