Answer:
14 or -22
Step-by-step explanation:
st=18
s=-4
-4+18=14
so t can be at 14
or -4-18=-22
t can be at -22
All the fractions are factors of 30
1/3 X 10, 1/5 X 6, 1/2 X 15.
/\10/30, /\6/30, /\15/30
Add all of them together: 31/30
Then you simplify the total: 1+1/30
1 and 1/30 is the answer
Answer:
x = ±3
Step-by-step explanation:
(3x² + 27)(x² - 9) = 0
(3x² + 27)(x + 3)(x - 3) = 0
3x² = -27
x² = -9
x = √-9 (this will result in an imaginary number)
x + 3 = 0
x = -3
x - 3 = 0
x = 3
768
Step-by-step explanation:
divide
Isolate the variable by dividing each side by factors that dont contain the variable x=9
