Find the perimeter of the window P=4* length of the side
P=4*22=88 inches
Cost = $2.00 * Perimeter
Cost = 2*88 =$176
Answer:
(3) the polynomial has degree 3. If it were a complex coefficient polynomial, then the answer is 2.
Step-by-step explanation:
I am assuming it is a real coefficient polynomial, otherwise the answer will be 2. Since 3i is a root, then so is its conjugate -3i, therefore the polynomial is a multiple of (x-(-1)) *(x-3i) * (x-(-3i)) = (x+1) * (x²+9), which has real coefficients. Hence, its degree is atleast 3. Option (3) is correct

Answer: -12
Work: Since -4 is in parentheses, I did -4 / 5 first. After doing the division, I had gotten -0.8. I multiplied -0.8 by 15, and had gotten -12.
