You have to combine like terms, so the variable (x, y, s, d, c....) and the exponents must be the same in order to combine them.
For example:
x² + x³ Since they don't have the same exponent, you can't combine them
y² + 3y² = 4y²
23x + x = 24x
4. 2s² + 1 + s² - 2s + 1 You can rearrange it if it makes it easier
2s² + s² - 2s + 1 + 1 = 3s² - 2s + 2
5. 5t² - 2t - 1 - (3t² - 5t + 7) Distribute/multiply the - to (3t² - 5t + 7)
5t² - 2t - 1 - 3t² + 5t - 7 = 2t² + 3t - 8
Do the same for #9 and #10, and you should get:
9. 2k² + 5k - 9
10. 6y³ - 7y² - 6y - 12
Answer:
9.8 Cubed
9.8 cubed, (9.8)3, is the number you get when multiplying 9.8 times 9.8 times 9.8.
It can also be looked at as exponentiation involving base 9.8 and exponent 3.
The term is usually pronounced 3rd power of 9.8 or 9.8 to the third power.
The cube of 9.8 is an imperfect cube because 941.192 is the product of the three equal numbers 9.8 which contain decimals.
It can be written as 9.8 × 9.8 × 9.8 or in exponential form.

Do you need to find what t is? If so, do 300 divided by 60 to get the t isolated. which is, 5.
you can check by doing 60*5 which is 300
