Answer:
1.25 + 5.25
Step-by-step explanation:
combine the similar stuff
(2.75j - 1.5j) +(2.25 + 3)
1.25j + 5.25
To solve this polynomial equation, we first factor the left side.
To factor x² + 8x + 12 = 0, look for factors of 12 that add to 8.
These factors are 6 and 2 so we have (x + 6)(x + 2) = 0.
So either x + 6 = 0 or x + 2 = 0 and solving for
x in each equation, our answer is {-6, -2}.
Answer:
x=6
Step-by-step explanation:
12x + 3=11x+9 corresponding angle
12x-11x=9-3
x=6
Recall that the sum of all 3 angles of a triangle is 180. So,
82 + 45 + x = 180>> 127 + x = 180
>> x = 180 - 127
>> x = 53 (final answer)
