Just subtitute 5 as x in the equation given for f.
2(5)+8=18.
Answer:
-2
Step-by-step explanation:
1. Distribute: -3x + 6x + 3 = x-1
2. Combine like terms: 3x + 3 = x-1
3. Subtract 3 on both sides: 3x = x-4
4. Subtract x on both sides: 2x = -4
5. Divide each side by 2: x = -2
6. Check by plugging in -2 to the equation:
Answer:
A.
Step-by-step explanation:
Simplify the radical by breaking up the radicand up into a product of known factors, assuming positive real numbers.
