MN = √2
it comes from √(1^2 + 1^2) = √2 (use phytagoras)
LK = 2 x MN = 2 √2
NK = √(2^2 + 1^2) = √5
ML = NK = √5
so the perimeter
√2 + 2 √2 + √5 + √5
3 √2 + 2 √5
Take second equation here,
2x + 9 = -12
2x = -12 - 9
2x = -21
Multiply by 2,
4x = -42
Now, substitute the vaue of 4x in 1st equation,
-42 - y = 2
-y = 2 + 42
y = -44
In short, Your Answer would be -44
Hope this helps!
Answer:
3*( 8-2n)=5n
The number is 24/11
Step-by-step explanation:
three times
3*
the difference of eight and twice a number
3*( 8-2n)
is five times the number
3*( 8-2n)=5n
To solve
Distribute
3*8 -3*2n = 5n
24 -6n = 5n
Add 6n to each side
24 - 6n +6n = 5n +6n
24 = 11n
Divide each side by 11
24/11 = 11n/11
24/11 =n
The number is 24/11
