The x-intercept is when y=0, so we plug that in our equation,
. +12 on both sides to get
. Divide by -8 to get
Answer:

Approximating to a more number of decimal places gives a better estimation of the exact value.
For 45.367 cm, we approximated to three decimal places or five significant figures.
For 43.43 cm, the approximation is done to four decimal places.
Therefore the measurement 45.367cm is more precise because it has a relatively smaller error.
Let's solve ~
