Select the two values of x that are roots of this equation. X2 + 2x - 5 = 0

LenaWriter [7]

Answer:

$x=-1+\sqrt{6 }$

$x=-1-\sqrt{6 }$

Step-by-step explanation:

$x=\frac{-b±\sqrt{b^{2}-4ac } }{2a}$

Ignore the A before the ±. It wouldn't let me type it correctly.

x² + 2x - 5 = 0

a = 1

b = 2

c = - 5

$x=\frac{-2±\sqrt{2^{2}-4((1)(-5)) } }{2(1)}$

$x=\frac{-2±\sqrt{4-4((1)(-5)) } }{2(1)}$

$x=\frac{-2±\sqrt{4+20 } }{2(1)}$

$x=\frac{-2±\sqrt{24 } }{2}$

$x=\frac{-2±\sqrt{(2)(12) } }{2}$

$x=\frac{-2±\sqrt{(2)(2)(6) } }{2}$

$x=\frac{-2±\sqrt{(2)(2)(2)(3) } }{2}$

$x=\frac{-2±(\sqrt{2} )(\sqrt{2})(\sqrt{(2)(3) )} }{2}$

$x=\frac{-2±2\sqrt{6 } }{2}$

Two separate equations

$x=\frac{-2+2\sqrt{6 } }{2}$

$x=\frac{-2-2\sqrt{6 } }{2}$

$x=-1+\sqrt{6 }$

$x=-1-\sqrt{6 }$

What is the volume of the following solid figure? 21 in cubed 42 inches cubed 56 in cubed 6 in cubed.

olya-2409 [2.1K]

Specifically, that is a triangular right regular prism.
Prism Volume = Area of Base • Height
The base area = (1/2) * 3 * 2 = 3 inchesHeight is 7 inches.Volume = 3 * 7 inches = 21 cubic inchesThe first answer is the correct one.

Margo can purchase tile at a store for $0.79 per tile and rent a tile saw for $24. At another store she can borrow the tile saw

Monica [59]

$0.79 t + 24 =1.19t \\ \\ 1.19t - 0.79t =24 \\ \\ 0.4t =24 \\ \\ t =60 \\ \\ \\ \sf So, ~if~he~buys~60~tiles, ~then~the~price~will~be~the~same.$
