You need to use foil here (first, outer, inner, last).
gxg=g^2
gx2=2g
7xg=7g
7x2=14
g^2-2g-7g+14 then simplify g^2-9g+14 is the answer

Select the two values of x that are roots of this equation.<br> 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

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

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

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

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

Answer:

You will need to buy 5 1.50lb bags of sugar to make your recipe.

Step-by-step explanation:

This problem can be solved by consecutive rules of three.

A large recipe calls for 3.18kg of sugar. Your bags of sugar are measured in pounds (lb). Remembering that 1kg=2.20462lb

How many lbs of sugar you will need to buy?

1 kg - 2.20462lb

3.18 kg - x lb

$x = 3.18*2.20462$

$x = 7 lb$

How many 1.50lb bags of sugar will you need to buy to make your recipe?

1 bag - 1.50 lb

x bags - 7 lb

$1.5x = 7$

$x = \frac{7}{1.5}$

$x = 4.67$

You will need to buy 5 1.50lb bags of sugar to make your recipe.
