I think it is the fourth one
Easy, so absolute value makes anything inside into positive
|x|=2
therefor x=-2 or x=2 since it would be made posotive
answer is -2 and 2
Answer:
x = 6
Step-by-step explanation:
Let x = first number
x+4x = 30
5x = 30
Divide by 5
5x/5 =30/5
x = 6
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.
Thank you !
