Answer:
4
cm
Step-by-step explanation:
The diagonal divides the square into 2 right angles with legs s and the diagonal as the hypotenuse.
Using Pythagoras' identity in the right triangle , then
s² + s² = 8²
2s² = 64 ( divide both sides by 2 )
s² = 32 ( take the square root of both sides )
s = 
= 4
Answer:
8(5*3)+(2*5)+(2*10)=360
Step-by-step explanation:
8(15)+(10)+(20)=
8(45)=
We have to find the value of the expression:
( x - y )² ; when x = 5 and y = - 1.
( 5 - ( - 1 ) )² = ( 5 + 1 )² = 6² = 36
Answer: the value is 36.
3x - 1 = 5x - 11
Add 1 to both sides.
3x = 5x - 10
Subtract 5x from both sides.
-2x = -10
Divide by -2.
x = 5
