<u>Answer:</u>
<h3>(

) x (

) </h3>
<u>Step-by-step explanation:</u>
To find the area of a rectangle, we have to multiply the length with the width.
In the question, the given length is 'x' and the width given is 'x +7'
So, the area would be
(
) x (
)
The area = 
So, the equation to find the area of such a rectangle would be:-
(
) x (
)

Answer: x=9
Step-by-step explanation: rewrite the given equation with y=6, 2x + 3(6)=36
Now simplify 2x +18=36
Subtract 18 from both sides of the equal
2x=18
Now divide both sides by 2 and your answer is x=9
1.0
As x -> 0 2x -> 0, SqRt(2x) -> 0 & 3 SqRt(2x) -> 0
Hence:
3 SqRt(2x) + 1 -> 1.0
