Just multiply the parentheses by 4. So you end up with 12x-20. If your teacher wants you to simplify then go ahead and divide to get a simplified equation but if not, then you're set.

Given data

Total amount of the solution=  342 milliliters

14% is acid

Hence the amount of acid

Para embalar una caja se emplea 4,2 m de cinta adhesiva. ?Cuántas cajas se podrán embalar con tres rollos que tienen 3 hm, 7 dam
kompoz [17]

For this case, we perform the conversions:

First roll:

1 \ Hectometer --------> 100 \ meters\\3 \ Hectometer --------> x

x = \frac {3 * 100} {1}\\x = 300 \ meters.

We make a rule of three to determine the number of "c" boxes that can be packed with 300 meters of adhesive tape.

1 -----------> 4.2

c -----------> 300

c = \frac {300 * 1} {4.2}\\c = 71.42857143\\c = 71

You can pack 71 boxes.

Second roll:

1 \ Decametro --------> 10 \ meters\\7 \ Decameter --------> x\\x = \frac {7 * 10} {1}\\x = 70 \ meters.

We make a rule of three to determine the number of "c" boxes that can be packed with 70 meters of adhesive tape.

1 -----------> 4.2

c -----------> 70

c = \frac {70 * 1} {4.2}\\c = 16.66666667\\c = 16

You can pack 16 boxes.

Third roll:

1 -----------> 4.2

c -----------> 50

c = \frac {50 * 1} {4.2}\\c = 11.9047619\\c = 11

You can pack 11 boxes.

Thus, in total you can pack11 + 16 + 71 = 98 \ boxes

Answer:

98 boxes

Find the value of p so that the equation 2x²+PX_2=0
padilas [110]
Answer: P = 0

Explanation:

2x^2 + Px - 2 = 0
2x^2/2 + Px/2 - 2/2 = 0/2
x^2 + Px/2 - 1 = 0

If we plug P = 0

x^2 + 0x/2 - 1 = 0
x^2 + 0 - 1 = 0
x^2 - 1 = 0
(x - 1)(x + 1) = 0
