It would be an open circle with an arrow going to the right
3x-x+2=4
<span>P = t + r + s
P - r - s = t + r - r + s - s
P - r - s = t</span>
Cot(-x) = 1 / tan(-x)
Tan(-x) * 1 / tan(-x) = 1
Answer:
x=-1
Step-by-step explanation:
x^2+2x=16=0
Use the quadratic formula to find the solutions.
−b±√b2−4(ac)/
2a
Substitute the values
a=1, b=2, and c=−16 into the quadratic formula and solve for x
