Answer:

The easiest method I know is to let a graphing calculator show you the solutions. The graph shows solutions to be approximately -1.54 and 0.87.

Answer:

x=-\frac{1-\sqrt{13} }{3} ,-\frac{1+\sqrt{13} }{3}

0.87, -1.54

Step-by-step explanation:

3x^2+2x-4=0

Use the quadratic formula:

x=\frac{-b+\sqrt{b^2-4ac} }{2a} ,\frac{-b-\sqrt{b^2-4ac} }{2a}

x=\frac{-2+\sqrt{2^2-4*3*-4} }{2*3} ,\frac{-2-\sqrt{2^2-4*3*-4} }{2*3}

Simplify:

x=\frac{-2+2\sqrt{13} }{6} ,\frac{-2-2\sqrt{13} }{6}

x=-\frac{1-\sqrt{13} }{3} ,-\frac{1+\sqrt{13} }{3}

a right triangle has legs measuring 4.5 meters and 1.5 meters the lengths of the legs of a second triangle are proportional to t
MrRa [10]

One approach that might be a great help would be if you would look
at the choices ... those things at the bottom of the question that you
didn't give us.

-- One leg is 3 times the length of the other leg.

-- Any right triangle that has one leg three times as long as the other
leg is similar to this triangle. 

I'll bet that if you look through the choices, you'll find one there.

Help me to solve thisssss​
m_a_m_a [10]

Answer:

(a + 3)

Step-by-step explanation:

a³ - 9a = a(a² - 9) = a(a + 3)(a - 3)

a² + a - 6 = (a - 2)(a + 3)

a⁴ + 27a = a(a³ + 27) = a(a - 3)(a² + 6a + 9) = a(a - 3)(a + 3)(a + 3)

HCF = (a + 3)

Hope it helps.
