1407.43cm³ V=πr2h=π·82·7≈1407.43351cm³
To solve for x, you need to do inverse operations to both sides. (also, you need to make 2 possibilities for the absolute value)
8 |x+7-3| = 5
Divide both sides by 8 and simplify like terms:
|x+4| = 5/8
Then, you need to separate into 2 different equations like this:
x +4 = 5/8 and
x + 4 = -5/8
Then, solving for x like this:
x = 5/8-4
x = -5/8-4
Which gets you
x = -3.375 and
x = -4.625
Hope this helped!
By the way, I'm getting closer to leveling up, so if you liked my answer, you could reward me with brainliest answer. That'd be great!
Answer:
(x - 2)(x² + 2x + 4)
Step-by-step explanation:
A difference of cubes factors in general as
• a³ - b³ = (a - b)(a² + ab + b² )
note 8 = 2³ = 8 ⇒ b = 2 , with a = x
Hence
x³ - 8
= x³ - 2³
= (x - 2)(x² + 2x + 2²) = (x - 2)(x² + 2x + 4)
Step-by-step explanation:
Pears manu have = 16
After sten gives = 16 + 10 = 26
Then manu gave to Klara = 26 - 8 = 18
The answer is 18
Manu have 18 Pears left
