What is really answer please help ​
Reika [66]

Answer:

4±√5

EXPLAINED ANSWER:

Since the variable is a binomial and it is squared, we apply square root on both side, and apply the ± sign on the right side (since the solution of a square root can be both positive and negative), and later pass the 4 positive to the other side.

√25 can be (5)(5) or (-5)(-5)

My name is Ann [436]

\bf ~~~~~~~~~~~~\textit{distance between 2 points}&#10;\\\\&#10;A(\stackrel{x_1}{-4}~,~\stackrel{y_1}{2})\qquad&#10;B(\stackrel{x_2}{12}~,~\stackrel{y_2}{4})\qquad \qquad&#10;d = \sqrt{( x_2- x_1)^2 + ( y_2- y_1)^2}&#10;\\\\\\&#10;AB=\sqrt{[12-(-14)]^2+[4-2]^2}\implies AB=\sqrt{(12+14)^2+(4-2)^2}&#10;\\\\\\&#10;AB=\sqrt{26^2+2^2}\implies AB=\sqrt{680}

CONSTRUCTION Carlos is building a screen door. The height of the door is I foot more than twice its width. What is the width of
-BARSIC- [3]

Answer:

<h2>width = 3 feet</h2>

Step-by-step explanation:

Let h be the height of the door

and w be its width

The statement “The height of the door is I foot more than twice its width”

can be translated mathematically like this :  h = 2w + 1

Let’s solve the equation for w:

h = 2w + 1

⇔ 2w = h - 1

\Leftrightarrow w=\frac{h-1}{2}

now , if the door is 7 feet high then it’s width is equal to :

\Rightarrow \frac{7-1}{2} =\frac{6}{2} =3 \ ft
