There were two containers of oil. There was twice as much oil in the second container as in the first one. After using 13 liters

Iteru [2.4K]

Answer:

48 liters

Step-by-step explanation:

First container = x

Second container has twice as much oil.

Second container = 2x

13 liters of oil was used from first container.

x - 13

7 liters of oil was used from the second container.

2x - 7

Second container has 3 times more oil than the first one.

2x - 7 = 3(x - 13)

x - 7 = 3(x - 13)

x - 7 = 3x - 39

2x = 32

x = 16

First container = 16 liters

second container = 16 x 2 = 32 liters

Total = 16 + 32 = 48 liters

Solve the quadratic equation by factoring 9x2+24+20=4

AnnyKZ [126]

Answer:

Final answer is $x=-\frac{4}{3}$ and $x=-\frac{4}{3}$ .

Step-by-step explanation:

Given equation is $9x^2+24x+20=4$ .

Now we need to solve that by factoring.

$9x^2+24x+20=4$

$9x^2+24x+20-4=0$

$9x^2+24x+16=0$

$9x^2+12x+12x+16=0$

$3x(3x+4)+4(3x+4)=0$

$(3x+4)(3x+4)=0$

$(3x+4)=0$ , $(3x+4)=0$

$3x+4=0$ , $3x+4=0$

$3x=-4$ , $3x=-4$

$x=-\frac{4}{3}$ , $x=-\frac{4}{3}$

Hence final answer is $x=-\frac{4}{3}$ and $x=-\frac{4}{3}$ .
