Answer:
n^2 - n - 12 = (n+3)(n-4)
Step-by-step explanation:
3 times - 4 = -12 ( two numbers when multiplied = -12, when added=-1)
3 + -4 = -1
Answer:
1.5 + 1.3228756555323i
1.5 - 1.3228756555323i
Step-by-step explanation:
y = ax^2 + bx + c
a = 1, b = -3, c = 4
Using the quadractic formula:

Note: Kindly ignore the A in the above solution ^
Hence, there is no real solution. It has complex roots.

Answer:
Step-by-step explanation:
Measures of angles are,
m∠A = (2x)°
m∠B = (x + 14)°
m∠C = (x - 38)°
By triangle sum theorem,
m∠A + m∠B + m∠C = 180°
2x + (x + 14) + (x - 38) = 180
(2x + x + x) + (14 - 38) = 180
4x - 24 = 180
4x = 204
x = 51
m∠A = 2(51)° = 102°
m∠B = (51 + 14)° = 65°
m∠C = (51 - 38)° = 13°
Answer:
it is B
