Answer:
a). x = 9
b). m∠ABC = 27°
c). m∠CBD = 153°
Step-by-step explanation:
1). Property of linear pair of angles states, "sum of linear pair of angles is 180°"
3x + (15x + 18) = 180°
18x + 18 = 180
18x = 180 - 18
18x = 162
x = 9
2). m∠ABC = 3x°
= 3×9
= 27°
3). m∠CBD = (15x + 18)°
= (15×9 + 18)°
= (135 + 18)°
= 153°

Answer:
y⁴ - 2y²
General Formulas and Concepts:
<u>Pre-Algebra</u>
<u>Algebra I</u>
Step-by-step explanation:
<u>Step 1: Define</u>
4y⁴ - (3y² + 3y⁴) + y²
<u>Step 2: Simplify</u>
- Distribute negative: 4y⁴ - 3y² - 3y⁴ + y²
- Combine like terms (y⁴): y⁴ - 3y² + y²
- Combine like terms (y²): y⁴ - 2y²
