We can start with "All real number," then we eliminate certain value what would cause zero in denominator;
Here, we have denominator of √(2x+8)
We need to exclude value of x from real number such that √(2x+8) = 0 So solve for x here;
√(2x+8) = 0
[√(2x+8) ]² = 0²
2x+8 = 0
2x = -8
x = -4
So we cannot have x to be -4, otherwise denominator would be zero.
So exclude -4 from "All real number"
Now we have domain of (-∞, -4) U (-4, ∞) or All real number; x ≠ -4.
Answer: c I’m pretty sure
Step-by-step explanation: errr
idk the answer to be honest,but i think it is b and i had got 990 so i hope this work
Answer:
<h2>A = 3x²</h2>
Step-by-step explanation:
The formula fo an area of a triangle:
b - base
h - height
We have
x - base
6x - height
Substitute:
