X/(x^2+3x+2) - 1/((x+2)(x+1))
x/(x^2+3x+2) - 1/(x^2+3x+2)
(x - 1)/(x^2+3x+2)
Answer: Choice D
I think it’s the first one
Answer:
A)
Step-by-step explanation:
Let me know if anything is unclear :)
Complementary angles are angles whose sum is 90 degrees.
90 - 67 = 23
23 degrees is the measure of its complementary angle.
Answer:
B = 129
Step-by-step explanation:
Opposite angles of a parallelogram are equal (or congruent)
A and C are both 51.
All angles in a parallelogram equal 360
Take both the known angles and substract from 360, than divide by 2.
B = (360 - 51 - 51)/2
B = 129
