Answer:
16.703
Step-by-step explanation:
right angle triangle thus we use puthagoras theorem to find the unknown length.
By converse of pythagoras theorem,
c² = a² + b²
c = √a² + b²
where c is the hypothenuse, a and b can be any 2 side of the right angle triangle
so x = √c² - a² = √ 20² - 11² ≈ 16.703 (or u can use calculator to find the long string of decimals and then round off on your own)
Answer: The answer is C
Step-by-step explanation:
Answer:
3x(3x + 2)
Step-by-step explanation:
(4x2 - 2x) - (-5x2 - 8x)
= 4x2 - 2x + 5x2 + 8x.
= 4x2 + 5x2 - 2x + 8x.
= 9x2 + 6x.
= 3x(3x + 2).
I hope it is right.
