The statment is correct but if you have to work out the value of x you need a total amount of the purchase without that or atleast some sort of value it is not possible to work out
Answer:
1506meters
Step-by-step explanation:
1hour-60minutes
which means half an hour is 30minutes,so it's more like they are asking you to find how far the swimmer can swim in 30minutes
50.2-1min
x -30min
x=50.2×30
x=1506meters
Sang grew more. and by 17/40 ( I could be wrong)
First, let's construct an algebraic equation to formally find the answer:
Let x represent (the value of) the unknown number.
x²= 5x + 24 --- This equation shows that the (positive) number's square equals 24 more than 5 times the number.
Now we can solve for x (the number):
x² = 5x + 24
x² - 5x - 24 = 0
(x + 3)(x - 8) = 0
x = -3, 8
Therefore, this means that x (the number ) can be either -3 OR 8. Both will satisfy the description.
Hope this helps!
Area=legnth times width=31
the frame must go around the frame with equal legnth, x
so
the total area (meaning the frame +picture) is 5+x by 6+x
31=(5+x)(6+x)
expand
31=30+11x+x^2
minus 31 both sides
0=-1+11x+x^2
x^2+11x-1=0
answer is third one
