the fractions can be turned to decimals easily, 4/5 is 0.8 and 2/5 is 0.4 . divide those decimals together and you get 2.
Answer:
It is not equivalent.
Step-by-step explanation:
You have to expand the brackets :
(x-4)(x+3)
= x(x) + x(3) - 4(x) - 4(3)
= x² + 3x - 4x - 12
= x² - x - 12
Therefore, x² - x - 12 / (x-4)(x+3) is not equivalent to x² - 4x - 12.
B or c for the equation because it is 1-n
43,000 in scientific notation is 4.3 x 10^4
Filling in the given information, you are asked to find "r" from
64π = 4πr²
Dividing by 4π gives
16 = r²
And taking the square root tells you
4 = r
The appropriate choice is ...
C. 4
