Answer:
2
x
Step-by-step explanation:
The diagonal divides the square into 2 right angles with legs s and hypotenuse x
Using Pythagoras' identity on one of the right triangles, then
s² + s² = x²
2s² = x² ( divide both sides by 2 )
s² = 
( take the square root of both sides )
s = 
= 
Thus
perimeter = 4s = 4 × = 
Multiply numerator/ denominator by
perimeter = 
= 2 x
Answer:
True
Step-by-step explanation:
3x8=24
24-63=-39
39=39
Hence, the equation is true.
<span>Simplify (3x22)*divided*6+[28-(4)^2]=
</span>the answer is A 23
x - y = - 11 .............( 1 )
y + 7 = - 2x ...............( 2 )
from equation ( 1 )
x - y = - 11
x = -11 + y ...........( 3)
putting x in equation ( 2 )
y + 7 = - 2 x
y + 7 = -2 ( -11 + y ) y + 7 = 22 - 2 y y + 2 y =22 - 7
3 y = 15 y = 15 / 3
putting value of y in equation 3
x = -11+ ( 13 /5 ) x = -33 /3 + 15 / 3 ( l.c.m)
x = -17 / 5
check
x = -11 + y
- 17 / 5 = -11 + 13 / 5
-17 /5 = -17 / 5
The Gcf is finding the greatest numbers the lcm is finding the least factor
and the are the same because your finding the common number> (means same number)
