=3(3z)2-3
=3(9z2)-3
=27z^2-3
=3(9z^2-1)
=3(3z+1)(3z-1)
16.4 would be the greatest and 15.6 would be the least due to 2.5% equaling 0.4 and adding and subtracting it from 16.
Answer:
Area = 16.8 * 7 / 2 = 58.8 ft2
Step-by-step explanation:
Have
18.2^2 = 7^2 + a^2
-> a^2 = 18.2^2 - 7^2
-> a^2 = 282.24
-> a = 16.8
Area = 16.8 * 7 / 2 = 58.8 ft2
tenths because 42.02 it would be tenths the first decimal is tenths and second is hundreths
Answer:
(2+5)2-52
=7× 2-52
=14-52
= -42
not in this list but that's right answer
