Hey there, Natethegreat13!

The correct answer should be A
If it takes \frac{1}{5} hours (which is 24 minutes) to fill one tenth of the tank, then to fill 10 tanks, it would be \frac{1}{5} * 10 and you get a total of 2 hours to fill the tank.

Thank you for using Brainly.
See you soon!

If 1/10 of the tank is filled in 1/5 of an hour, then multiplying both of those by 5 you would get 5/10 of a tank being filled in a full hour, or answer choice A. Hope this helps! By the way, sorry for the incorrect answer a couple years ago :)

Which represents x2 – 12x + 36 in factored form?
alexandr402 [8]

Answer:

(x - 6)(x - 6)

Step-by-step explanation:

The given quadratic equation is $ x^2 - 12x + 36 = 0 $.

A quadratic equation can be factored in the form $ (x - a)(x - b) $ where $ -a $ and $ -b $ will form the roots of the equation.

Here the roots are: $ +6 , +6 $.

The factored form would simply be:  $ (x - 6) (x - 6) $.

What is the area? Please explain steps so I can attempt to understand
yarga [219]

Answer:

12 \sqrt{2}

Step-by-step explanation:

you can use hypotenuse formula

45-45-90 isosceles right triangle

so, 45= x

x² + x² = 24²

2x² = 24²

x²= 24.12

x= \sqrt{288}  = 12 \sqrt{2}

or :

you can use this rule: if you see a 45 45 90 isosceles right triagngle (you can look picture) 45=a cm and 90 = a\sqrt{2}

cm

so ;

a \sqrt{2}  = 24

a= 12 \sqrt{2}

hope this helps ^-^

What the expression (4f-3+2g)-(4g+2)
galben [10]
For this question you can say: 
4f -3 +2g - 4g -2
so now you can simplify and find the answer:
4f -3 -2g -2 = 4f -2g -5
and that's the answer :)))
I hope this is helpful
