The volume of a rectangular prism is given by the product of its dimension: let w, h, l be the width, height and length of the prism, we have
![V = whl](https://tex.z-dn.net/?f=V%20%3D%20whl)
In your case, everything is given except the width:
![144 = w\cdot 3 \cdot 12 \iff 144 = 36w \iff w = \dfrac{144}{36} = 4](https://tex.z-dn.net/?f=144%20%3D%20w%5Ccdot%203%20%5Ccdot%2012%20%5Ciff%20144%20%3D%2036w%20%5Ciff%20w%20%3D%20%5Cdfrac%7B144%7D%7B36%7D%20%3D%204)
Answer:
w = 4 m
Step-by-step explanation:
The volume (V) of a cuboid is
V = lwh ( l is length, w is width and h is height )
Given V = 144 m³, then
lwh = 144 ( substitute l = 3 and h = 12 )
3 × w × 12 = 144
36w = 144 ( divide both sides by 36 )
w = 4

Answer:
4x^2 − 4x −1 + 11 / x+1
Step-by-step explanation:
The answer is
4x^2 − 4x −1 + 11 / x+1
Answer:
(x + 2)²
Step-by-step explanation:
Given
x² + 4x + 4 ← is a perfect square of the form
(x + a)² = x² + 2ax + a²
Compare like terms
a² = 4 ⇒ a =
= 2, thus
x² + 4x + 4 = (x + 2)²
I believe the answer is the last option
hope that helps, God bless!
You would have to change that 5% into 0.05 and multiple it by 2 you get 0.1.Now,multiple 0.1 by 20000 and you get 2000.
