Answer:
-0.25
Step-by-step explanation:
→ Find fg(x)
2 ( x + 1 )² = 2x² + 4x + 2
→ Find gf(x)
2x² + 1
→ Equate them
2x² + 1 = 2x² + 4x+ 2
→ Move everything to the right hand side
0 = 4x + 1
→ Solve
x = -0.25
Answer: <em>In the upper triangle x = 33° and in the lower triangle x = 128°</em>
Step-by-step explanation:
<em><u>Upper triangle:
</u></em>
<em>x = (180° - 114°) ÷ 2 = 33°</em>
<em><u>Lower triangle:</u></em>
<em>x = 180° - 26° × 2 = 128°</em>
Answer:
4x² - 20x + 16
Step-by-step explanation:
Given
(4x - 4)(x - 4)
Each term in the second factor is multiplied by each term in the first factor, that is
4x(x - 4) - 4(x - 4) ← distribute both parenthesis
= 4x² - 16x - 4x + 16 ← collect like terms
= 4x² - 20x + 16
