Answer:
Sandy should have evaluated (-2)³ as -8
Step-by-step explanation:
(-2)³ (6 - 3) - 5(2 + 3) = -8 · 3 - 5 · 5 = - 24 - 25 = - 49
Because:
(-2) · (-2) · (-2) = 4 · (-2) = - 8
God with you!!!
We can re arrange this:
(-5)*(4) * x^6 * x * x^8 * y * y^6 * z^9 * z^9
using exponent properties
we can get
-20 x^15 y^7 z^18
as our simplified answer.
If a $24 dvd is marked down by 30% then the cost of the dvd would be 70% of the original cost. 100% - 30% = 70%
70% of 24 can be expressed as 0.7 x 24.
The answer is $16.80.
Hope this helps :)
