A square has a perimeter of 40 m what is the length of each side
zubka84 [21]

Answer:

10m

Step-by-step explanation:

<u>Perimeter</u> means adding up all of the sides of a shape.

One property of a square is that <u>all lengths of a square are the same</u>.

We also know squares have <u>4 sides</u>.

<u />

Lets set up an expression to solve the length for each side with variable S representing the length of a side:

4 * S = 40

Divide each side by 4:

S = 10

Therefore, each side of the square has a length 10m

Grace [21]

Answer:

Step-by-step explanation:

Rearrange the terms and take out a common factor of 4

4(8x^2 + 2x + 1)

I think this is as far down as you want to take it. It gives an imaginary root which you may not be familiar with.

What’s the length of the new fence?
natulia [17]
We apply the Pythagorean theorem twice and obtain:
 12 ^ 2 = x ^ 2 + (15-d) ^ 2
 9 ^ 2 = x ^ 2 + d ^ 2
 We observe that it is a system of two equations with two unknowns whose solutions are:
 (x, d) = (-36/5, 27/5)
 (x, d) = (36/5, 27/5)
 We ignore the negative solution, therefore, the solution is:
 (x, d) = (36/5, 27/5)
 Answer:
 
The length of the new fence is:
 
x = 36/5 meters

Use substitution to solve<br>y=2x+1 <br>y=x-5
nirvana33 [79]
2x+1 = x-5
-x -x
X+1 = -5
-1 -1

X = -6

2(-6) +1= y
-12+1= y

-11 = y

-11 = -12+1
-11 = -6-5
