Answer:
each side of the square is 25cm
Step-by-step explanation:
this is because of two things:
1. a square has equal sides
2. the perimeter is all the sides added together.
so if you call the length of one side x, you can make this equation:
x + x + x + x = 100
<em>combine like terms</em>
4x = 100
<em>divide both sides by 4</em>
x = 100/4
x = 25
(2^3)^-5 = 2^(3 x -5) = 2^-15 = 1/2^15
12/7 = x/20

Answer:
perpendicular
Step-by-step explanation:
if you find the slope of the points, they are completely opposite 4/3 and -3/4
1 Simplify 7x+16+47x+16+4 to 7x+207x+20<span> 7x+20=x<span>7x+20=x</span></span>
2 Subtract 7x from both sides<span> 20=x-7x<span>20=x−7x</span></span>
3 Simplify <span>x-7x<span>x−7x</span></span> to <span>-6x<span>−6x</span></span>
<span>20=-6x<span>20=−6x</span></span>
4 Divide both sides by −6 -20/6=x
5 Simplify 20/6 to 10/3 -10/3=x
6 Switch sides
x=-10/3<span><span><span> </span></span></span>
