Answer:
The answer is -23.
Step-by-step explanation:
substitute x with -4. multiply and add regularaly.
There is three terms in the expression "n2+6n-3".
In Algebra a term is either a single number or variable, or numbers and variables multiplied together. Terms are separated by + or − signs, or sometimes by divide.
That's a little messy :)
If that is: -1/[3^(n-1)]
-1, -1/3, -1/9, -1/27, -1/81
Area of the shaded region = Area <span>of a square - Area of a circle
</span>
Side of a square = 2r
Area of a square = (2r)² = 4r²
Area of a circle = πr²
Area of the shaded region = 4r² - πr² = r²(4-π)
