The perimeter is the length of all 6 sides added together. So say each side equals 2. Then your equation would be 2+2+2+2+2+2. or. 6x2. 6x would be your answer

Each side is x units long. There are 6 sides. So we add up all the sides to get the perimeter.
x+x+x + x+x+x
there are six copies of x being added

Simplifying that expression above leads to 6*x or simply 6x. Multiplication is a shortcut for repeated addition. Instead of saying 2+2+2+2, we can write 4*2

Answer: Choice C) 6x

A rectangle and a square have the same perimeter. the rectangle is of length 6cm and has an area of 48cm², find the length of th

<em>The length of the square that has the same perimeter as the rectangle is of length 6cm and area of 48cm² is 7cm</em>

<h2>Explanation:</h2>

Let's call:

$A_{s}:Area \ of \ square \\ \\ A_{r}:Area \ of \ rectangle \\ \\ P_{s}:Perimeter \ of \ square \\ \\ P_{r}:Perimeter \ of \ rectangle$

From the question, we know that:

<em>A rectangle and a square have the same perimeter.</em>

So:

$P_{s}=P_{r}$

Moreover:

<em>The rectangle is of length 6cm and has an area of 48cm²</em>

Accordingly:

$For \ Rectangle: \\ \\ L:Length \\ W:Width \\ \\ A_{r}=L\times W \\ \\ 48=6W \\ \\ W=8$

Also:

$A_{s}=s^2 \\ \\ S:Side \ of \ square$

From the statement of perimeters:

$P_{s}=P_{r} \\ \\ \\ But: \\ \\ P_{s}=4s \\ \\ P_{r}=2W+2L \\ \\ \\ Then: \\ \\ 4s=2W+2L \\ \\ \\ But: \ W=8 \ and \ L=6 \\ \\ 4s=2(8)+2(6) \\ \\ 4s=16+12 \\ \\ 4s=28 \\ \\ \boxed{s=7cm}$

Finally, <em>the length of the square that has the same perimeter as the rectangle is of length 6cm and area of 48cm² is 7cm</em>

Solve for x in the equation 2x2 + 3x-7 = x2 + 5x+39

yulyashka [42]

Answer: x=1+√47 or x=1−√47 (Assuming that the "2x2" is 2x^2)

Step-by-step explanation:

Step 1: Subtract x^2+5x+39 from both sides.

2x2+3x−7−(x2+5x+39)=x2+5x+39−(x2+5x+39)

x2−2x−46=0

For this equation: a=1, b=-2, c=-46

1x2+−2x+−46=0

Step 2: Use quadratic formula with a=1, b=-2, c=-46.

x=1+√47 or x=1−√47
