You are correct!
90*58=5220!
You can check this by doing 5220/90 and you should get 58.
I hope this helps;)

We will have to divide the length the coach wants you to swim by the length of your pool to find how many laps you must swim. However, we need to first convert 3 km to meters by multiplying by 1000 (because 1 km = 1000 m).
3 * 1000 = 3000 m
Now we can divide.
You will need to swim 120 laps (not a realistic number).

so
first we get rid of square root then
make the equation equal to zero becaues if
xy=0 then x or/and y=0
squareroot(y-1)+3=y
isolate the squareroot
subtrac 3 from boht sides
squareroot(y-1)=y-3
square both sides (since they are equal, you should be able to square both sides and still make it true)
(squareroot(y-1))^2=(y-3)^2
(y-1)=(y-3)(y-3)
y-1=y^2-6y+9
subtrac y from both sides
-1=y^2-7y+9
add 1 to both sides
0=y^2-7y+10
find what two number multiply to make 10 and add to get -7
the answer is -2 and -5
0=(y-5)(y-2)
therfore
y-5=0
and/or
y-2=0
therefor
y=5 or/and 2 might work
let's try out 2
square root(2-1)+3=2
square root(1)+3=2
1+3=2
false
so 2 doesn't work
let's try 5
squareroot(5-1)+3=5
squareroot(4)+3=5
2+3=5
5=5
true
y=5

4/12 ÷ 4/4 = 1/3
4/12 in simplest form , well 4/4 is equal to 1 , and 12 of course divided = / by 4 = 3 , because 4*3=12 , and 4*1=4 , so 4/4=1 and 12/4=3.
i hope this answered your question.

Answer:
(1/2)(8x³ + x² - 6x + 12)
Step-by-step explanation:
Next time, please share the possible answer choices. Thanks.
Multiplying all four terms of the given polynomial by 2 results in
x² - 6x + 8x³ + 12
Rearranging these terms in descending order by powers of x:
(1/2)(8x³ + x² - 6x + 12)
Note that we cannot just ignore that '2' in the denominator, because the given polynomial is an expression, not an equation.
