Step-by-step explanation:
4x² - 12x + 9 = 5 → 4x² - 12x + 4 = 0 → x² - 3x + 1 = 0
∆ = b² - 4ac → ∆ = (-3)² -4(1)(1) = 9 - 4 = 5
x = (-(-3) ± √5)/2(1) = (3 ± √5)/2
x² - 3x + 1 = 0 → (x - 3/2)² - 9/4 + 1 = 0 → (x - 3/2)² = 5/4 → x - 3/2 = ±√5 / 2 → x = ½( 3 ± √5)
One factor of 12 is 2. The other factors of 12 are 3, 4, and 6.
Answer:
14.7
Step-by-step explanation:
5:3
5units:3units
5+3=8
8 units
4qt=8units
divide by 8 both sides
1/2qt=1unit
red=5unit
red=5*1/2
red=5/2qt
d
lime green=3unit
lime green=3*1/2
lime green=3/2qt
not sure what the ratio of the blue paint to the yellow paint is
I do know that
when b=amount of blue paint in quarts
yo need 5/2qt red, b qt blue, and y qt yellow, where b+y=3/2qt
and the ratio is
5:b:y, where b+y=3
can't solve fully without ration of the the blue to yellow
I think it is C ............
