Answer:
Step-by-step explanation:
The square root of a positive number cannot be negative. False. There are two square roots, one positive and one negative.
All positive numbers have two square roots. True. See above.
0 18 = 9 because 9(2) = 18. Unable to answer; "0 81" is invalid. Note that
√81 = ±9
49 = 7 because 7(7) = 49. Invalid statement. 49 never equals 7. Perhaps you meant √49 = ±7
25 = 5 because 52= 25. Invalid statement. Perhaps you meant √25 = ±5.
Please, before you do any more square root problems, learn how to type the " √ " symbol or equivalent, such as "sqrt( "

Answer:
65:52
Step-by-step explanation:
5 + 4=9
117/9=13
13*5=65
13*4=52
to make sure the answer is right 65+52=117
so the answer is 65:52
The unknown vertex is on the perpendicular bisector of the opposite side. So the x coordinate is the same as that of the midpoint, x=(18+52)/2=35.
