Answer:
4t^3-t-4
Step-by-step explanation:
(-3t^3-5t)+(7t^3+4t-4)
Combine like terms
-3t^3+7t^3 +4t -5t-4
4t^3 -t -4
Decimals are no fun. It might be a good idea to get rid of the decimals as a first step.
Notice that the smallest decimal value is in the THOUSANDTHS PLACE. So if we multiply both sides by 1000, that should do the trick.
1000( 0.007x + 0.03 ) = 1000( 0.1 )
With each term, we'll move the decimal 3 places.
That's what it means to multiply by 1000.
7x + 30 = 100
From that point the problem becomes quite a bit easier.
Subtract 30,
7x = 70
Divide by 7 as a final step,
x = 10
Hope that helps :)
Try this formula
A squared plus B squared equals to C squared
the answer would be C, 35
The common factor of 24a^3c and 3a is 3a
24a^3c /3a = 8a^2c
3a/3a = 1
