- [Right Triangles Only] Pythagorean Theorem: a² + b² = c²
Step-by-step explanation:
<u>Step 1: Define</u>
We are given a right triangle. We can use PT to find the missing side.
<u>Step 2: Identify Variables</u>
Leg <em>a</em> = 5
Leg <em>b</em> = <em>x</em>
Hypotenuse <em>c</em> = 12
<u>Step 3: Solve for </u><em><u>x</u></em>
- Substitute: 5² + x² = 12²
- Isolate <em>x</em> term: x² = 12² - 5²
- Exponents: x² = 144 - 25
- Subtract: x² = 119
- Isolate <em>x</em>: x = √119
Answer:
Yes.
Step-by-step explanation:
Set the equations equal to each other to determine their equality.
-4[3(x - 7)] = 6(14 - 2x)
Distribute the 3 and the 6 into their respective parenthesis.
-4[3x - 21] = 84 - 12x
Distribute the -4 into the brackets.
-12x + 84
Rearrange the equations.
84 - 12x = 84 - 12x
Since the equations come out to be the same thing on both sides so that any value satisfies it, the equations are equivalent.
