Which expressions are equivalent to 5p+3p+(-9)5p+3p+(−9)5, p, plus, 3, p, plus, (, minus, 9, )? Choose all answers that apply:
Lemur [1.5K]

Answer:

Option B.

Step-by-step explanation:

The given expression is

5p+3p+(-9)

We need to find an expression which is equivalent to the given expression.

Combine like terms.

(5p+3p)-9

8p-9

The simplified form of given expression is 8p-9. So, option A is incorrect.

In option B, the given expression

3(p+(-3))+5p

3(p-3)+5p

Using distributive property, we get

3p-9+5p

Combined liker terms.

(5p+3p)-9

8p-9

It is same as the simplified form of given expression.

Therefore, the expression 3(p+(-3))+5p is equivalent to the given expression and correct option is B.

Simplify the expression please.
pishuonlain [190]

Answer:

tanx·secx

Step-by-step explanation:

To simply this, you can begin by factoring sin x out of the numerator to become:

\frac{sinx (sin^{2}x +cos^{2} x)}{cos^{2} x}

Now, using Pythagorean Trig Identities, we know that sin²x+cos²x equals 1. We can substitute this to make the equation become:

\frac{sinx}{cos^{2}x }

First of all, we can convert \frac{sinx}{cosx} to tanx. However, we have a remaining \frac{1}{cosx} which, using reciprocal identities, will become sec x.

Finally, we get our answer as tanx·secx.

cluponka [151]
The picture shows how this would look as a triangle.
In this case, we would use tan. x is the opposite side, and 80 is adjacent.
tan(85.7) = x/80
13.299.. = x/80
x = 1,064 feet
