<h3>Answer: \sf 3\dfrac{4}{31} \quad or \quad \dfrac{97}{31}</h3>

-------------------------------------------------------------------------------------------------------

The given expression:

\sf \dfrac{2b + 3c^2}{4a^2 - 2b}

Here given <u>a = 8</u>, <u>b = 4</u>, and <u>c = 16</u>

<u />

Inserting this values

\sf \dfrac{2(4) + 3(16)^2}{4(8)^2 - 2(4)}

Simplify following

\sf \dfrac{8 + 3(256)}{4(64) - 8}

Distribute inside parenthesis

\sf \dfrac{8 + 768}{256 - 8}

Add/Subtract similar terms

\sf \dfrac{776}{248}

Simplify following, in improper fraction

\sf \dfrac{97}{31}

In mixed fraction, answer:

\sf 3\dfrac{4}{31}

Two pools are being filled with water. To start, the first pool contains 2200
Lynna [10]

2200 + 21.25X = 1840 +32.50X

subtract 1840 from each side

360+ 21.25X= 32.50X

subtract 21.25x from each side

360=11.25X

x= 360/11.25 = 32 minutes pool will have the same amount

 

21.25*32 = 680+2200 = 2880 liters

32.5*32 = 1040 + 1840=2880 liters

 

 it will take 32 minutes and they will have 2880 liters each

. The volume of a box is 405 cubic units. The length is x units, the width 4 units greater than the length, and the height is 9
lukranit [14]

Answer:

length = 5

width = 9

Step-by-step explanation:

V = lwh

let 'x' = length

let '4+x' = width

9 = height

405 = 9x(4+x)

405 = 36x + 9x²

this is a quadratic equation:  9x² + 36x - 405 = 0

factor out a 9 to get:

9(x² + 4x - 45) = 0

9(x-5)(x+9) = 0

one root is 5 and the other is -9

since distance cannot be negative we use 5 as the length and 9 is the width
