Answer:
Step-by-step explanation:
There are thirty-nine palindromic numbers between 10 and 400.
Listed, they are: 11, 22, 33, 44, 55, 66, 77, 88, 99, 101, 111, 121, 131, 141, 151, 161, 171, 181, 191, 202, 212, 222, 232, 242, 252, 262, 272, 282, 292, 303, 313, 323, 333, 343, 353, 363, 373, 383, and 393.
P = 101
2(l+w)
2(30.2+20.3)
101
18a^2
Multiply the numbers together. Multiply the variables together.
(-3a)(-6a) = (-3) * (-6) * a * a = 18a^2
-3 times -6 = 18 since negative times negative is positive, and 3 * 6 = 18.
Also a * a = a^2.
Answer: 18a^2
