Answer :
To find the product of (x + 8)(x – 10)
We know that
(x + a)(x + b) = x2 + (a + b)x + ab
In the expression (x + 8)(x – 10)
a = 8
b = -10
a + b = 8- 10 = -2
ab = 8 × (-10) = – 80
Substitute the values in the above equation
(x + 8)(x – 10) = x2 + (8 – 10)x + 8 × (-10)
(x + 8)(x – 10) = x2 – 2x – 80.

Answer:
The answer is J.
Step-by-step explanation:
Set it Up as a proportion. To do this you do the length of one triangle divided by the height of the same triangle. then you do the same for the other triangle. You get (29/h) = (8.5/5)
The function and its inverse are exactly the same. You find the inverse of a function by switching the x and the y and then solving for the new y. If your function is y = -x + 5 and you switch the x and the y, you get x = -y +5. Now solve for the new y to get y = -x + 5. The domain and range for those is all real numbers.
