Answer:
12
Step-by-step explanation:
We can use the pythagorean theorem giving us:
a^2+b^2=c^2
(6sqr2)^2 + (6sqr2)^2 = c^2
72+72=c^2
144=c^2
12=c
-√4 + √(-48) + √121 + √(-108)
= -√(2²) + √(-1 • 3 • 4²) + √(11²) + √(-1 • 2² • 3³)
= -2 + 4√3 i + 11 + 6√3 i
= 9 + 10√3 i
Statement given :
→Sara says "If you subtract 11 from my number and multiply the difference by -3 , the result is -54 .
<u>To</u><u> </u><u>f</u><u>ind</u><u> </u>:
SOLUTION :
Let us take Sara's Number be “x”.
★According to Question,
→ x - 11×(-3)= -54
→ x + 33 = -54
→ x = -54-33
→ x = (-87)
let's verify our number,and check whether it's correct or not !
x - 11×(-3)= -54
<u>Putt</u><u>ing</u> <u>the</u> <u>value</u> <u>of</u> <u>x</u>
(-87) - 11 × (-3)= -54
(-87) + 33 = -54
(-54) = -54
Hence, The L.H.S. = R.H.S.
Thus,our number is Verified.
