Answer:
(B) (7x - 6 ) ( 7x + 6)
Step-by-step explanation:
49x^2 - 36
This is the difference of squares
(7x)^2 - 6^2
We can factor this as
(a^2 -b^2) =(a-b) (a+b)
(7x)^2 - 6^2 = (7x-6) (7x+6)
Error=100 calculated/actual
error=100 (175-97.5) / 97.5
error=100 (77.5) / 97.5
error=7750 / 97.5
error=77500 / 975
error=3100 / 39
error=79.5% <-- Estimated
Answer:
64 degrees
Step-by-step explanation:
The interior angles of a triangle must add up to 180 degrees. So, we can add up the other two, known angles to get 116. Subtract 116 from 180 (180-116) to get 64.
