90.629 is what you get when you divide 725 and 8
Hello :)
They are basically asking which one of these expansion would give you the right answer.
So first you would have to solve the expression, by using foil.
(4x+1)(2x^2-2)
F- first
4x · 2x^2
O- outer
+4x · (-2)
I- inner
+1 · 2x^2
L- last
Put all of the expressions together.
the answer would be A
The coefficient of n-9 is 1 because is the number in front of the variable n
Answer:
<em>n = 6 </em>
Step-by-step explanation:
2.3 × = (1 × 10³)(2.3 × )
(1 × 10³)(2.3 × ) = (1)(2.3) × (10³)( ) = 2.3 ×
2.3 × = 2.3 × ⇒ 3 + n = 9 ⇒ <em>n = 6</em>
