Answer:

A. Vertical multiplication

Step-by-step explanation:

What happens:

What happens here is that each term on the first parenthesis multiply each term on the second paranthesis, that is, the application of the distributive property, which is the most widely used procedure to solve a vertical multiplication, meaning that the answer is given by option a.

If it takes Charlie 45 minutes walking at 2.5 km/hr to get to the chocolate factory and it takes Willy Wonka 15 minutes walking

Mrac [35]

Answer:

Willy Wonka

Step-by-step explanation:

Given data

it takes Charlie 45 minutes walking at 2.5 km/hr

speed = distance /time

distance= speed*time

distance= 2.5*45

distance= 112.5 km

it takes Willy Wonka 15 minutes walking at 3.5 km/hr

distance= speed*time

distance= 3.5*15

distance= 52.5 km

Hence Willy Wonka stays closer

Answer is : 8v^3+ 14v^2+11v+3
For cubic feet

Solution

Formula : volume base area x height

So base area = 4v^2 +5v+3
Height = 2v+1

So multiply

Volume =(4v^2+5v+3) x(2v+ 1)

The rest is below

WILL GIVE BRAINLIEST!!! Given tan(theta) = 4/3 and pi < theta < (3pi)/2, find cos(2theta).

babymother [125]

Answer: $\cos 2 \theta = \dfrac{-7}{25}$

Step-by-step explanation:

Given: $\tan \theta = \dfrac{4}{3}$ and $\pi < \theta< \dfrac{3\pi }{2}$

To find: $\cos 2 \theta$

Now as we know

$\cos 2x = \dfrac{1- \tan ^2 x}{1+ \tan ^2 x}$

So we have

$\cos 2 \theta = \dfrac{1-(\dfrac{4}{3} )^2}{1+(\dfrac{4}{3} )^2} \\\\\Rightarrow \cos 2 \theta = \dfrac{1- \dfrac{16}{9} }{1+ \dfrac{16}{9} } = \dfrac{\dfrac{9-16}{9} }{\dfrac{9+16}{9}} = \dfrac{-7}{25}$

Therefore d. is the correct option

Hence , $\cos 2 \theta = \dfrac{-7}{25}$
