Answer:

It will take 4 hours and 48 minutes with both pipes.

Step-by-step explanation:

Add their rates of filling

1st pipe's rate = ( 1 tank ) / ( 12 hrs )

2nd pipe's rate = ( 1 tank ) / ( 8 hrs )

Let, t = hrs to fill tank using both pipes

(1 / 12) + (1 / 8) = (1 / t)

Multiply both sides by 24t

2t + 3t = 24

5t = 24

t = 4.8

0.8 x 60 = 48

It will take 4 hours and 48 minutes with both pipes

Find the following algebra, I am in class and plz give explanation
Lelechka [254]

1) Solving 4a+4b-ac-bc we get (a+b)(4-c)

2) Solving 16a^4-8b we get 8(2a^4-b)

3) Solving x^2-8x+15 we get (x-3)(x-5)

Step-by-step explanation:

We need to solve the following expressions:

1) 4a+4b-ac-bc

We will solve this expression by factoring common terms:

4a+4b-ac-bc

Factoring 4 from 4a+4b and -c from -ac-bc

4(a+b)-c(a+b)

Taking common term

(a+b)(4-c)

2) 16a^4-8b

We will solve this expression by factoring common terms:

16a^4-8b

Taking 8 as common term:

8(2a^4-b)

3) x^2-8x+15

We can solve the expression by breaking the middle term into 2

x^2-3x-5x+15\\Finding\,\,common:\\=x(x-3)-5(x-3)\\=(x-3)(x-5)
