Answer:

Step-by-step explanation:

Sum = 5

Product = -6

Factors = (-1) ; 6    {-1+ 6 = 5  & (-1)*6 = -6}

3x² + 5x - 2 = 0

3x² - x + 6x - 2 = 0

x(3x - 1) + 2(3x - 1) = 0

(3x - 1)(x + 2) = 0

A triangular pyramid is formed from three right triangles as shown below.
Bess [88]

Answer:

  FH = 108

Step-by-step explanation:

The given figure requires we use the Pythagorean theorem to write two relations involving right triangle side lengths. The Pythagorean theorem tells us the square of the hypotenuse is the sum of the squares of the other two sides.

__

<h3>Triangle EGH:</h3>

  EG² = GH² +HE²

  GH² = EG² -HE² = 53² -28² = 2025 . . . . . solve for GH², use given values

<h3>Triangle FGH:</h3>

  FG² = GH² +FH²

  FH² = FG² -GH² = 117² -2025 = 11664 . . . . solve for FH², use known values

  FH = √11664 = 108 . . . . . take the square root

The length FH is 108.

If x varies directly as y and x=3 when y = 8, find the value of y when x=9
padilas [110]

Answer: Y =24

Step-by-step explanation:first get the constant. X=KY substituting x and y in the equation is 3=K8 Therefore K = 3/8 =0.375

If x is 9 find y when the constant k is 0.375 from the equation x=ky

Is Y = X÷K is 9÷0.375 =24.

9) If x=-4 is a zero of a polynomial p(x), then the zero of p(x² - 6x + 5) is​
spin [16.1K]

If x=-4 is a zero of p(x), then we can write

p(x) = (x + 4) q(x)

for another polynomial q(x).

Note that x^2 - 6x + 5 = (x - 5)(x - 1). Then

p(x^2 - 6x + 5) = p\bigg((x-5)(x-1)\bigg) \\\\ ~~~~~~~~~~~~ = ((x - 5)(x-1) + 4) q\bigg((x-5)(x-1)\bigg) \\\\ ~~~~~~~~~~~~ = (x^2 - 6x + 9) q(x^2 - 6x + 5) \\\\ ~~~~~~~~~~~~ = (x - 3)^2 q(x^2 - 6x + 5)

so that \boxed{x = 3} is a root of p(x^2 - 6x + 5).
