Write an equivalent expression by distributing the "minus−" sign outside the parentheses:
-(-3y+8.2z-5.4)
7 answers
3y - 8.2z + 5.4
Subtract-5x^2-9x-5 from 4x^2-5x+3
To subtract -5x^2 - 9x - 5 from 4x^2 - 5x + 3, we can distribute the negative sign to each term inside the parentheses:
4x^2 - 5x + 3 - (-5x^2 - 9x - 5)
Simplifying,
4x^2 - 5x + 3 +5x^2 + 9x + 5
Now, we can combine like terms:
(4x^2 + 5x^2) + (-5x + 9x) + (3 + 5)
9x^2 + 4x + 8
4x^2 - 5x + 3 - (-5x^2 - 9x - 5)
Simplifying,
4x^2 - 5x + 3 +5x^2 + 9x + 5
Now, we can combine like terms:
(4x^2 + 5x^2) + (-5x + 9x) + (3 + 5)
9x^2 + 4x + 8
so what is the final answer?
The final answer is 9x^2 + 4x + 8.

Expanded form:
Answer:
The expanded form of (4b)^3 is 4b * 4b * 4b.
Simplifying, we have (4 * 4 * 4) * (b * b * b).
This equals 64 * b^3.
Therefore, the simplified expression is 64b^3.
Simplifying, we have (4 * 4 * 4) * (b * b * b).
This equals 64 * b^3.
Therefore, the simplified expression is 64b^3.
