Answer:
Step-by-step explanation:
m∠1 = 2x and m∠2 = -3x+235
angle 1 and angle 2 are supplementary angle so they add up to 180°
m∠1 +m∠2 = 180°
2x -3x+235 = 180°
-x = 180-235
x=35
m∠1 = 2x = 2*35 = 70°
m∠2 = -3x+235 = -3*35 +235 = 235-105 = 130°
Answer:
the third from the top option
Step-by-step explanation:
Answer:
x = StartFraction negative 5 plus or minus StartRoot 5 EndRoot Over 2 EndFraction
Step-by-step explanation:
we know that
The formula to solve a quadratic equation of the form
is equal to
in this problem we have
equate the function to zero
so
substitute in the formula
therefore
x = StartFraction negative 5 plus or minus StartRoot 5 EndRoot Over 2 EndFraction
The first step we take is to factor out a GCF:
2d(d³ + 3d² - 9d - 27)
Now, we can factor what's in the parenthesis by grouping (don't forget to keep the 2d we factored out):
2d[d²(d+3) -9(d+3)]
2d(d²-9)(d+3)
d²-9 can still be factored because it is the difference of two squares:
2d(d+9)(d-9)(d+3)
That is the completely factored form.
Hello :
the system of equations can be used to find the roots of the equation 12x^3-5x=2x^2+x+6 is : y = 12x^3-5x
y = 2x^2+x+6
