Answer
-8fc+2f
Step-by-step explanation:
Answer option C
27x³+64y³
it's written as
(3x)³ +(4y)³
Now by using identify
<h3>a³+b³=(a+b)(a²-ab+b²)</h3>
(3x)³+(4y)³= (3x+4y){(3x)² - 3x*4y+(4y)²}
→ (3x+4y)( 9x²-12xy+16y²)
<u>So required answer is option C</u>
Answer:
x = 8
Step-by-step explanation:
3x + 2 + 7x + 8 = 90
10x + 10 = 90
10x = 80
x = 8
Check: 3x + 2 = 3(8) + 2 = 26°
7x + 8 = 7(8) + 8 = 56 + 8 = 64°
sin 26 = cos 64
Volume is length times width times height
