Question

which is different? find \both\ answers.
find (ac + cb).
find (bc - ac).
find (ab).
find (ca + bc).
the \different\ answer is (square) the \same\ answer is (square)

Explanation:

Step1: Identify segment lengths

Given $AC = 3$ and $BC=7$.

Step2: Calculate $AC + CB$

$AC + CB=3 + 7=10$.

Step3: Calculate $BC - AC$

$BC - AC=7 - 3 = 4$.

Step4: Calculate $AB$

By the segment - addition postulate, $AB=AC + CB=10$.

Step5: Calculate $CA+BC$

Since $CA = AC$, $CA + BC=3 + 7=10$.

Answer:

The "different" answer is Find $BC - AC$. The "same" answer is Find $AC + CB$, Find $AB$, Find $CA + BC$.
