Answer 1

\[t^3-20r \div r ~~~~:r=4~;~~t=2\]
start by plugging in the values:
\[2^2-20(4)\div4\] then you would evaluate, remember to follow the order of operations

Answer 2

@agreene ok

Answer 3

@agreene can u show me how to work a problem out like this

Answer 4

like this one?

Answer 5

yes

Answer 6

@agreene

Answer 7

you will want to follow the order of operations: PEMDAS. \[()\rightarrow a^a\rightarrow\times\rightarrow\div\rightarrow+\rightarrow-\]
so no (), then look at exponents \(2^2\) then multiplication \(20(4)\) and then division \(20(4) \div 4\) then finish with the subtraction
