First, change the mixed number into an improper fraction : 1 3/4 = 7/4
Then, write -7 as an improper fraction. You now have this expression:
-7/1 x 7/4.
Multiply each numerator and denominator, and you get your answer: -49/4, which reduces to -12 and 1/4, or -12.25
Answer:
x = -3, -6.
Step-by-step explanation:
3x2 + 27x + 54 = 0
Divide through by 3:
x^2 + 9x + 18 = 0
(x + 3)(x + 6) = 0
x = -3, -6.
Answer:
