Your answer is the first option because the word "of" means multiplying.
hope this helped :)
To the hundredth place, or second decimal this would be 1.004_
So this will become 1.0
You would multiply the # of pounds (5) by the price ($1.99). So, 5 x 1.99 = $9.95.
1 ) 3 t ( t + 2 ) - 3 t² =
= 3 t² + 6 t - 3 t² = 6 t = 6 · 19 = 114
2 ) - ( 3 a - 2 b ) - 3 ( - a- b ) =
= - 3 a + 2 b + 3 a + 3 b = 5 b
The second one it's double.
