-3m*n^2 because n*n is n squared, and -3m is still there
Answer:
(x+12)
Step-by-step explanation:
x2 + 8x - 48
x2 + 12x - 4x - 48
(x-4)(x+12)
Step-by-step explanation:
For a
Let the another angle be x then
x + 51° = 90° {being complementary angles }
x = 90° - 51°
x = 39°
For b
Let the another angle be x then
x + 113° = 180° {being supplementary angles }
x = 180° - 113°
x = 67°
Answer:
-11/24
Step-by-step explanation:
i used a fraction calculator, but basically you’ll want to find the least common denominator (lcd) for both of the fractions and then work with them like that. the lcd is 24, so multiply 5/12 by 2/2 and 7/8 by 3/3 and you’ll have 10/24 minus 21/24. then all you gotta do now, is subtract the numerator and you’ll have -11/24
