9.21 - (-5.51)
9.21 + 5.51 = 14.72
The distance is 14.72
My graphing app says the perimeter is 11.04 +2.24 ≈ 13.3 units, corresponding to the 3rd selection.
Answer:
c = d/a - b
General Formulas and Concepts:
<u>Pre-Algebra</u>
Step-by-step explanation:
<u>Step 1: Define</u>
a(c + b) = d
<u>Step 2: Solve for </u><em><u>c</u></em>
- Divide <em>a</em> on both sides: c + b = d/a
- Subtract <em>b</em> on both sides; c = d/a - b
