Anastasy [175]

Answer:

$\boxed{\sf \ \ \ x = -8 \ or \ x = -4 \ \ \ }$

Step-by-step explanation:

Hello,

$4x^2+48x+128=0\\ 4(x^2+12x+32)=0\\ x^2+12x+32=0\\ (x+6)^2 - 36 + 32= 0\\\\ (x+6)^2-4=0\\ (x+6+2)(x+6-2)=0\\ (x+8)(x+4) = 0\\ x = -8 \ or \ x = -4$

A garden hose supplies 36 gallons of water in 3 minutes. Use a table of equivalent ratios to show the garden hoses water flow in

Eduardwww [97]

Answer:

1 minute:12 gallons

1 gallon:0.0833 minutes

Step-by-step explanation:

-Let x be the number of minutes and y be the number of gallons.

-Given that 36 gallons flow in 3 minutes, our table ratios can be calculated and represented as below:

$3 \ minutes=36\ gallons\\\\\therefore 1 \ minute=\frac{36}{3}=12 \ gallons\\\\2 \ minutes =12\ gallons \times 2= 24 \ gallons$

#We then calculate minutes per gallon as below:

$36\ gallons =3\ minutes\\\\\therefore 1 \ gallon=\frac{3}{36}\\\\=0.0833\ minutes$

Hence,the flow of gallons per minute and minutes per gallon are represented in table ratios as attached.
