(x+3)^2=4

GalinKa [24]

Answer:

x = -1, -5

Step-by-step explanation:

${(x + 3)}^{2} = 4 \\ = > {x}^{2} + 2 \times x \times 3 + {3}^{2} = 4 \\ = > {x}^{2} + 6x + 9 = 4 \\ = > {x}^{2} + 6x = 4 - 9 \\ = > {x}^{2} + 6x = - 5 \\ = > {x}^{2} + 6x + 5 = 0 \\ = > {x}^{2} + 5x + x + 5 = 0 \\ = > x(x + 5) + 1(x + 5) = 0 \\ = > (x + 1)(x + 5) \\ = > x = - 1 \: \: or \: \: - 5$

Hope it helps.

Bought three books: 150, if one book cost 50% more than the other two combined what was the price of the more expensive book

EleoNora [17]

Two cheaper books = x
more expensive = 1.5x
so, 2.5x=150
150/2.5=x=60
therefore the more expensive book = 90

Specify three fractions with different denominators that have a LCD of 24 then arrange the fractions in order from least to grea

romanna [79]

We can just guess 20/24, 10 / 24 and 8 / 24

From the least to the greatest:

8/24, 10/24, 20/24

8/24 = 1/3 10/24 = 5/12 20/24 = 5/6

So it is:

1/3, 5/12, 5/6

I hope this helps.

A line contains the points (4,2) and (0,1). What is the equation of the line?

Troyanec [42]

$\bf (\stackrel{x_1}{4}~,~\stackrel{y_1}{2})\qquad (\stackrel{x_2}{0}~,~\stackrel{y_2}{1}) ~\hfill \stackrel{slope}{m}\implies \cfrac{\stackrel{rise} {\stackrel{y_2}{1}-\stackrel{y1}{2}}}{\underset{run} {\underset{x_2}{0}-\underset{x_1}{4}}}\implies \cfrac{-1}{-4}\implies \cfrac{1}{4}$

$\bf \begin{array}{|c|ll} \cline{1-1} \textit{point-slope form}\\ \cline{1-1} \\ y-y_1=m(x-x_1) \\\\ \cline{1-1} \end{array}\implies y-\stackrel{y_1}{2}=\stackrel{m}{\cfrac{1}{4}}(x-\stackrel{x_1}{4}) \\\\\\ y-2=\cfrac{1}{4}x-1\implies y = \cfrac{1}{4}x+1$
