Answer: volume of the cube is (7 cm)^3= 343 cm^3
so calculate the Volume of the water that is already in the tank
so l x w x h
4 x 18 x 12
=864cm^3 is in the tank
find the total volume of the tank:
6 x 18 x 12
=1296cm^3
and subtract the current from the total to find what you need:
1296cm^3 - 864cm^3
= 432 cm^3
you can also find how much you need by using the remaining 2cm from the height (6-4=2) and use the volume formula with 2 substituted as the height and you’ll get the same answer
Answer:
The answer is (4x - 3)/(x + 6)
Step-by-step explanation:
∵ (4x² - 7x + 3)/(x² + 5x - 6)
Factorize the numerator:
4x² - 7x + 3 = (4x - 3)(x - 1)
Factorize the denominator:
x² + 5x - 6 = (x - 1)(x + 6)
∴ (4x - 3)(x - 1)/(x - 1)(x + 6) ⇒ reduce (x - 1) from in up and down
∴ The answer is (4x - 3)/(x + 6) ⇒ the fourth answer
