Answer:
Step-by-step explanation:
We need to compare √8 and 4
<em>To compare the numbers they should both be in the same format</em>
<u>√8 is not a perfect square so we'll put number 4 under root</u>
<u>Now we compare</u>
So √8 is less than 4
I am assuming you do not mean The length of a triangle and you mean The length of a rectangle because the answer you given are the formula for the perimeter of a rectangle. With that said, the answer is D<span>.2w+2*(3w)112
The perimeter of a rectangle can be found by the following equation:
2L + 2W = P
OR
P = 2L + 2W
The equation </span>P = 2L + 2W is read perimeter = 2 times Length + 2 times width
The Question:
<span>The length of a rectangle is three times its width.if the perimeter is at its most 112 centimeters ,which is the greatest possible value of the the width.
</span>
The length of a rectangle
This means the perimeter
is
The word is means to use an equal sign
three times its width
This means 3 times w or 3w
The w = width
perimeter is at its most 112
This means <=
<= means less than or equal to
Ok so lets look at our equation
2L + 2W = P
2w + 2(3w) <= 112
Answer:
<h2>3x - y + 7 = 0</h2>
Step-by-step explanation:
The slope-intercept form of an equation of a line:
m - slope
b - y-intercept
Put the given y-intercept b = 7 and the coordinates of the point (-2, 1) to the equation:
<em>subtract 7 from both sides</em>
<em>divide both sides by (-2)</em>
We have the equation:
Convert it to the general form 
:
<em>subtract 3x and 7 from both sides</em>
<em>change the signs</em>
