Answer: =5x3+x2+6x−5
Step-by-step explanation:
To add or subtract radicals, the indices and what is inside the radical (called the radicand) must be exactly the same. If the indices and radicands are the same, then add or subtract the terms in front of each like radical.
Answer:
B
Step-by-step explanation:
calculating slope formula:
m = (y2-y1)/(x2-x1)
-7 - (-7) = -7 +7 = 0
-24 - (-6) = -24 +6 = -18
m = 0/-18 = 0
next time just look at the y. if they are the same the answer is always 0. if x is same the answer is undefined
