Answer:

L=6x^2-4x+5

P=12x^2-4x-2

Step-by-step explanation:

A=WL

So, we know the area is 6x^2-8x-30 and the width is 2x-6

Substitute

(6x^2-8x-30)=(2x-6)(L)

L=(6x^2-8x-30)/(2x-6

Divide

L=6x^2-4x+5

P=2L+2W

Substitute

P=2(6x^2-4x+5)+2(2x-6)

P=12×^2-8x+10+4x-12

Simplify

P=12x^2-4x-2

g My Notes Water flows from the bottom of a storage tank at a rate of r(t) = 200 − 4t liters per minute, where 0 ≤ t ≤ 50. Find
Arada [10]

Answer:

4,200 liters

Step-by-step explanation:

The flow rate is given by:

r(t) = 200 - 4t

Integrating the flow rate expression from t=0 to t=30 minutes, yields the total volume that flows out of the tank during that period:

\int\limits^{30}_0 {r(t)} = \int\limits^{30}_0 {(200 - 4t} )\, dt \\V=(200t - 2t^2)|_0^{30}\\V= (200*30 -2*30^2)-(200*0 -2*0^2)\\V=4,200\ liters

4,200 liters of water flow from the tank during the first 30 minutes.

5/6=x-10/3x+6 solution?
Ivan

Answer:

\boxed{ \bold{ \huge{ \boxed{ \sf{x =  - 10}}}}}

Step-by-step explanation:

\sf{ \frac{5}{6}  =  \frac{x - 10}{3x + 6} }

Apply cross product property

⇒\sf{5(3x + 6) = 6( x - 10)}

Distribute 5 through the parentheses

⇒\sf{15x + 30 = 6( x - 10)}

Distribute 6 through the parentheses

⇒\sf{15x + 30 = 6x - 60}

Move 6x to left hand side and change it's sign

⇒\sf{15x - 6x  + 30 =  - 60}

Collect like terms

⇒\sf{9x + 30 =  - 60}

Move 30 to right hand side and change it's sign

⇒\sf{9x =  - 60 - 30}

Calculate

⇒\sf{9x =  - 90}

Divide both sides of the equation by 9

⇒\sf{ \frac{9x}{9}  =   \frac{ - 90}{9} }

Calculate

⇒\sf{x =  - 10}

Hope I helped!

Best regards!!
