Step-by-step explanation:
<u>Step 1: Define Equation</u>
2x + 10 = -4x - 9
<u>Step 2: Solve for </u><em><u>x</u></em>
- Add 4x on both sides: 6x + 10 = -9
- Subtract 10 on both sides: 6x = -19
- Divide 6 on both sides: x = -19/6
<u>Step 3: Check</u>
<em>Plug in x into the original equation to verify it's a solution.</em>
- Substitute in <em>x</em>: 2(-19/6) + 10 = -4(-19/6) - 9
- Multiply: -19/3 + 10 = 38/3 - 9
- Add/Subtract: 11/3 = 11/3
Here we see that 11/3 does indeed equal 11/3.
∴ x = -19/6 is the solution to the equation.
Step-by-step explanation:
I do not see your diagram. Triangles can be isosceles, scalene, equilateral, degenerate, etc.
Isosceles; 2 congruent sides and angles
Scalene: no congruent sides and angles
Equilateral: 3 congruent sides and angles
Degenerate: The sum of two sides is equal to the length of the other one, looks like a line segment.
