Answer:
x = 9 ⇒ second answer
Step-by-step explanation:
∵ (a + 3)(-2a² + 15a + 6) =
-2a³ + 15a² + 6a - 6a² + 45a + 18 =
-2a³ + 9a² + 51a + 18
∵ (a + 3)(-2a² + 15a + 6) = -2a³ + xa² + 51a + 18
∴ -2a³ + 9a² + 51a + 18 = -2a³ + xa² + 51a + 18
∴ x = 9
Answer:
One solution
Step-by-step explanation:
The only solution is x = 2/3
Y = -1.4
The simplest way to find the answer is to cancel out the x - values. Set both equations equal to zero.
10x + 8y + 24 = 0
5x - 6y - 2 = 0
Multiple the second equation by -2 so the x terms cancel out when you add them together.
10x + 8y + 24 = 0
-10x + 12y + 4 = 0
20y + 28 = 0
20y = -28
Y = -1.4
Answer: what is your question, is this your question bro
Step-by-step explanation:
Answer:
30 hours
Step-by-step explanation:
Distance = Speed * Time
We can use that formula to plug in the numbers given.
1778mi = 61.7mph * Time
1778/61.7 = 28.817 (approx.)
So the answer will be about 30 hours
