Which expression represents 4/5t(-10t)?

(A)-8t

(B)46/5t

(C)46/5t^2

(D)-8t^2

Answer 1

the best answer is option d

Explanation:

4/5 x -10 = -40/5 = -8

t x t = t^2

-8t^2

Answer 2

`\sf \: d) \: - 8 {t}^(2)`

Explanation:

Given expression,

`\sf \rightarrow \: (4)/(5)t \: ( - 10t )`

Let's simplify the expression,

`\sf \rightarrow \: (4)/(5) t \: ( - 10t) \:`

`\sf \rightarrow \: ( (4)/(5) * - 10)( {t} * t)`

`\sf \rightarrow \: ( ( - 40)/( \: 5) )( {t}^(2) )`

`\sf \rightarrow \: - 8{t}^(2)`

Hence, the option (d) is correct.
