1) f(x) + g(x)

= 7√x + 4 + 2√x - 2

= √x(7 + 2) + 2

= 9√x + 2  [ Final Answer ]

2) f(x) - g(x)

= 7√x + 4 - (2√x - 2)

= 7√x + 4 - 2√x + 2

= √x(7 - 2) + 6

= 5√x + 6   [ Final Answer ]

Hope this helps!

- | 1 - 5a | = 29<br> i need help and an explain on how to do it.
Sunny_sXe [5.5K]

Answer:

Well your using absolute value and everything in absolute value is positive so you get rid of the negative.

Step-by-step explanation:

So you distribute the negative into the absolute value equation . And it leaves you with

|-1+5a|=29 now you can solve

your subtract your -1 from both sides bc you are solving for a

that gives you

5a=30 then you divide 5 divided by 30 is what 6 so that’s your answer

a=6
