Answer:
x = 3 or x = 2 or x = -6
Step-by-step explanation:
Solve for x:
(x - 3) (x^2 + 4 x - 12) = 0
Split into two equations:
x - 3 = 0 or x^2 + 4 x - 12 = 0
Add 3 to both sides:
x = 3 or x^2 + 4 x - 12 = 0
The left hand side factors into a product with two terms:
x = 3 or (x - 2) (x + 6) = 0
Split into two equations:
x = 3 or x - 2 = 0 or x + 6 = 0
Add 2 to both sides:
x = 3 or x = 2 or x + 6 = 0
Subtract 6 from both sides:
Answer: x = 3 or x = 2 or x = -6
It would equal 5 x 10 ^ 10
because 10 ^ 10 is 10 billion and 9 x 10 billion is 90 billion and 4 x 10 billion is 40 billion. so, 90 billion - 40 billion. that's 50 billion, and that can be turned into 5 x 10 ^ 10.
Answer: I'm prett sure its c) 60, 90, and 120
Step-by-step explanation:
Answer:
∠ CFE and ∠ DFE are adjacent angles and are supplementary, sum to 180°
∠ CFE + 152° = 180° ( subtract 152° from both sides )
∠ CFE = 28°
Step-by-step explanation:
183/3: 61mph
The answer would be 61mph.
