(-4w² - 9n) - (-15w²)
Treat the minus sign in the middle as if it's -1 and distribute.
(-4w² - 9n) -1(-15w²) = (-4w² - 9n) +15w²

Take out parentheses -4w² - 9n +15w²
Combine like terms. Two of these terms have a w² so we put them together

11w² - 9n
That's as simplified as it could get

When you multiply a decimal by a power of ten,what is the relationship between the number of places the decimal point moves and
Ymorist [56]

Answer:

  it depends

Step-by-step explanation:

For positive powers of 10, the decimal point moves right 1 place for each zero in the power of 10.

<u>Example</u>:

  1.2345 × 10³ = 1.2345 × 1000 = 1234.5 × 1 = 1234.5

__

For negative powers of 10, the decimal point moves left 1 more place than there are zeros in the power of 10.

<u>Example</u>:

  1234.5 × 10⁻³ = 1234.5 × 0.001 = 1.2345

  there are 2 zeros in .001, but the decimal point moves 3 places, corresponding to the exponent of 3 in the power of 10.
