Answer:
8x-12
Step-by-step explanation:
I just rounded a bunch for your sister.
463 < 500 so 3463 rounds to 3000
216 < 500 so 4216 rounds to 4000
501>=500 so 2501 rounds to 3000
457<500 so 6457 rounds to 6000
625>=500 so 6625 rounds to 7000
adding up the estimates gives an estimated total: 23000
Answer:
congruent angles just have the same measurement, no matter what the degree is.
complementary angles are = to 90 degrees
supplementary angles are = to 180 degrees
(7.57)^-4 * (7.57)^4
Add the exponents and keep the base:
7.57^(-4 + 4)
7.57^0
Anything to the power of 0 is one.
