Answer:

65

Step-by-step explanation:

So a number (let's call that x) plus -43 is 22. In an equation:

x-43=22

To find the number, add 43 to both sides. The left cancels:

x=65

And we're done!

The product of a+3 and -2a^2+15a+6 is -2a^3+xa^2+51a+18. What is the value of x? Is it 8 ,9,12 or15?
Serggg [28]

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
