Write an equivalent expression by distributing the "minus−" sign outside the parentheses:

-(-3y+8.2z-5.4)

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

so what is the final answer?

The final answer is 9x^2 + 4x + 8.

Use multiplication to expand the expression below. Then compute and/or simplify.

(4b)^3
Press the dot⋅ button or type the * symbol on your keyboard to represent multiplication. Using times× for multiplication is inappropriate when xx may be used as a variable. For the answer, type the base, then use the a, to the power ba
b
button or type the ^ symbol for an exponent.

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.
