Answer:
yesssssssssss you're right
X^2 - 4x - 12 = x^2 + 2x - 6x - 12 = x(x + 2) - 6(x + 2) = (x - 6)(x + 2)
x^2 + 4x - 12 = x^2 - 2x + 6x - 12 = x(x - 2) + 6(x - 2) = (x - 2)(x + 6)
x^2 - x - 12 = x^2 + 3x - 4x - 12 = x(x + 3) - 4(x + 3) = (x - 4)(x + 3)
x^2 - 7x - 12 is prime.
Answer:
62 degrees
Step-by-step explanation:
the base angles are congruent and the sum of angles is 180 degrees
56 + 2x = 180
2x = 124
x = 62 degrees
Answer:
-2.27
Step-by-step explanation:
3x = -32 - 5
3x = - 37
x = - 12.333333333
x = 5 y - 1
substitute x value
- 12.333333 + 1 = 5 y
- 11 .333333 = 5y
- 11.333333 divided by 5 = - 2.27
