To find a positive and a negative angle coterminal with a given angle, you can add and subtract 360°.
-135° + 360° = 225°
Answer: A=x²+6x+8
Step-by-step explanation:
Since we are looking to find the area of the entire rectangle, we would use the formula . is length and is width. You would approach this problem like any other area of the rectangle problem, except you are dealing with polynomials instead.
Given:
<span>x^2 + y^2 + z^2 + 2x − 2y − 2z = 22
group the variables
x^2+2x + y^2-2y +z^2-2z = 22
then complete the squares
x^2+2x+1 </span>+ y^2-2y+1 + z^2-2z+1 = 22 +1 +1 +1
factor and simplify
(x+1)^2 + (y-1)^2 + (z-1)^2 = 5^2
Interpretation:
The centre of the sphere is at (-1,1,1) with a radius of 5
