Hey there!
The answer to this question is the perimeter of the pool.
x^2+4.24^2=7.07^2
x=5.66.
5.66+4.24+5.66+4.24=19.8
Thus, 19.82 is the correct answer!

Answer:
y = -2
Step-by-step explanation:
27 = 17 - 5y
27-17=17-5y-17
10=-5y
10/-5=-5y/-5
-2=y
Answer:
If you look over the steps you can see that until 4x + x + 3 = 18, evertything is dandy. But the step after that 4x + x =21 seems a bit fishy.
Think about it they subtract 3 from both sides so the first side is correct
4x + x, but they added 3 to the other side:
not
4x+x = 21
Then we solve for 4x + x = 15
To solve for y we use :
y = x+3
y = 3+3 = 6
so (3,6) is the right answer
It can be turned into 4•19/81 (mixed proper fractions) or in decimal 4.2346 (4dp)
We want to subtract 8x + 3 from -2x+5. We can create an expression to represent this.
-2x + 5 - (8x + 3).
After this, lets distribute the - sign (think of this like expanding something with -1).
-2x + 5 - 8x - 3
Lastly, we just need to combine like terms.
-2x + 5 - 8x - 3
Combine the 5 and -3 to get 2.
-2x + 2 - 8x
Combine the -2x and -8x to get -10x.
-10x + 2
The final answer to the question is therefore A.
