Answer:
f(x) = x⁴ - 8x³ + 25x² - 72x + 144
Step-by-step explanation:
f(x) = (x-4)²(x+3i)(x-3i)
= (x²-8x+16)(x²+9)
= x⁴ - 8x³ + 25x² - 72x + 144
I think the answer would be 8 but I'm not sure
Answer:
The fraction of frame did Monica paint blue is
Step-by-step explanation:
Given as :
The area of square frame = A = 24 square inches
Monica paint
of one side of the frame blue
Let the measure of one side of frame = x
So, <u>From Area of square</u>
Area = side × side
Or, A = x × x
Or, x ² = 24
∴ x =
= 2
So, Measure of each side = x = 2
Now, As Monica paint
of one side of the frame blue
So, The painted part =
× 2
∴ The painted part =
× 
I,e The fraction of painted blue = 
Hence, The fraction of frame did Monica paint blue is
