Answer:
A
Step-by-step explanation:
2x² + 5x = 12
2x² + 5x - 12 = 0
x² + 5x - 24 = 0
factors of 24 are 1, 2, 3, 4, 6, 8, 12, 24. the only pair that adds to 5 is 8 and 3
2x² - 3x + 8x - 12 = 0
split the equation and factor
2x² - 3x = 0 ||| 8x - 12 = 0
x(2x - 3) ||| 4(2x - 3)
therefore the pair is (2x - 3)(x + 4)
2x - 3 = 0
2x = 3
x = 3/2
or
x + 4 = 0
x = -4
5x-9 = 3x+3
2x-9 = 3
2x = 12
x= 6
plz mark branliest, hopoe this helps :)
The answer is a) -21 - 77i
It equals 81/ft because you add 3 feet +3 feet because 9 yards are equal to 3 feet
For this case we can make the following rule of three:
2 ml -------------> 50cm ^ 2
c -----------------> 325 cm ^ 2
From here, we clear the value of c.
We have then:
c = (325/50) * (2)
c = 13 ml
