Angles on a straight line add up to 180 degrees so
45 + 3x = 180
Subtract 45 from both sides to remove the 45 on the left
3x = 135
Then divide both sides by 3
x = 45
Answer is X = 45
Hi there! :)
Answer:

To simplify the process, convert each given weight into standard notation:
Lion:

Ant:

Divide the ant's weight from the lion's weight:

Convert to scientific notation: (use # of zeros to determine exponent)
Therefore, the correct answer is C.
The answer is (2x-1)(2x-3)
