Answer:
Step-by-step explanation:
if you know that the perimeter is 20,
then you have to divide by 4 to get the length of one side
20/4=5.
Draw the diagonal and write in it's length as x.
Use Pythagorean formula
Then know that a2+b2=c2
and use the two side lengths as a and b.
This gives you the equation
5^2+5^2=x^2.
Do the calculations and solve the equation.
25+25=x^2
50=x^2
√50=x.
Therefore x=√50 where x equals the length of the diagonal.

Step-by-step explanation:
the square root of 10 is approximately 3.16228
Answer:
6.06 x 
Step-by-step explanation:
(5.25 x 
) / (8.7 x 
)
= (5.25 x ) x( )/ (8.7 )
= (5.25 x 
)/ (8.7 )
= 0.606 x 
= 6.06 x
Answer:
y = 3x -5
Step-by-step explanation:
y = mx + b
for (5, 10)
b = y - mx = 10 - 3 x 5 = - 5
y = 3x -5
for (2,1)
check: 1 = 2 x 3 -5
