Question

solve the equation or formula for the indicated variable R=ts^2+3

a)s=under radical R-3/t (not under radical
b)s=everything under radical R-3/t
c)s=R (under radical)-3/t
d)s=everything under radical R/t-3

Thanks again I feel really stupid not being able to grade my teens paper

Answer 1

t s^2 = (R-3)

s^2 = (R-3)/t

s = plus or minus sqrt [(R-3)/t ]

Answer 2

Just did the quick check
B. -2 1/2
A. 7.5 and 22.5
A. always
B. s=everything under radical R-3/t
A. -70
