Answer:
If a quadrilateral is a parallelogram, then consecutive angles are supplementary. If both pairs of opposite sides of a quadrilateral are congruent, then the quadrilateral is a parallelogram.
Step-by-step explanation:
Well x^2+10x-3 is a quadratic so we are looking for its lowest point (minimum). If you graph it the answer is (-5, -28) so A. You can do it algebraicallly (x+5)=0. X=-5 and look at -28 for y. Either way you get A as the local minimum/ lowest point of graph.
Hey,
If you meant that

than

![= \sqrt[4]{111^{5}}](https://tex.z-dn.net/?f=%3D%20%20%5Csqrt%5B4%5D%7B111%5E%7B5%7D%7D%20%20)
but you can't find the exact number.
Hope this helps :) and don't forget to choose the brainliest please :)
The perimeter will be
.. P = 2√(16^2 +30^2) = 2*34 = 68
