I'll answer ur question but the image is blurry
The number is 1/6. 15 minus 3 = 12. 12 times 1/6 is 2
Fraction with x squared plus y cubed in the numerator and 2 plus x in the denominator.
3.8
14.83
19.58
23.5
I believe the answer is "true".
We can use pythagorean theorem:
a^2 + b^2 = c^2
4 + 9 = c^2
13 = c^2
sqrt of 13 = c
Hope this helps!
