The greatest common factor of two numbers is 4. The sum of the numbers is 76. What are the two numbers? A. 38 and 38 B. 12 and 6
Rashid [163]

Answer: B. 12 and 64

Option B:

Factors of 12 are: 1, 2 , 3, 4, 6, 12

Factors of 64 are: 1, 2, 4, 8, 16, 32 and 64.

as far as I can see it looks like you need two names for the angle formed..-->>

the angle would be acute

Write a polynomial function of least degree with integral coefficients that has the given zeros.
densk [106]
The zeroes are
0, -5, 3 + i (and its conjugate)

The factors are
x (x + 5) (x - (3 + i)) (x - (3 - i))
Expanding...
(x² + 5x)((x - 3) - i) ((x - 3) + i)
(x² + 5x)((x - 3)² - i²)
(x² + 5x)(x² - 6x + 9 - (-1))
(x² + 5x)(x² - 6x + 10)
x⁴ - 6x³ + 10x² + 5x³ - 30x² + 50x
x⁴ - x³ - 20x² + 50x
