Answer:

x=6

Step-by-step explanation:

-2(x + 4)= -20

<u>Divide both sides by -2:</u>

<u />x+4=\cfrac{-20}{-2}<u />

<u>Divide -20 by -2 = 10</u>

<u />x+4=10<u />

<u>Subtract 4 from both sides:</u>

<u />x=10-4<u />

<u />x=6<u />

students were asked to simplify the expression . two students' work is given. student a step 1: step 2: step 3: 1 tan2 θ step 4:
Whitepunk [10]

Student B is wrong , student A is correct in simplifying the expression .

Expression B must be simplified to cot θ .

Formulas to be used are :

1 - sin^{2} θ = cos^{2}θ

 1 - cot^{2}θ = tan^{2}θ .

Since , location of error is step 3 , we will start from there

[ ( 1 - sin^{2}θ ) / sin θ ] / cos θ    = [ ( 1 - sin^{2}θ ) / sin θ ] * [ 1 / cos θ ]

                          = ( 1 - sin^{2}θ ) / ( sin θ * cos θ )

               = cos^{2} θ / ( sin θ * cos θ )

                   = cot θ .

The difference between sixteen, and the product of seven and two
Monica [59]

Answer:

2

Step-by-step explanation:

If this product was written as an equation, it would look like this:

16 - 7 * 2

PEMDAS states that multiplication comes before addition. So, the first step in the equation is to multiply 7 and 2.

7 * 2 = 14

Now, the equation looks like:

16 - 14

All we need to do now is subtract 14 from 16.

16 - 14 = 2

So, the final answer is 2.
