The perimeter is 72 because all sides on a square are the same measurements so you just have to do 18 times 4 to get 72

HELP WILL MARK AS BRAINLIST
Alinara [238K]

Hi!

Given:

\frac{x}{-1} > -6

Multiply both sides by -1

x

<em>Notice the sign was flipped. This is because when you multiply or divide by a negative number, you must always flip the sign!</em>

<u>Now, for the graph:</u>

-------------------------------------------------------------------------------------------------------------

For < or > signs, it should be an open circle. For \leq or \geq signs, it should be closed.

Since x is less than 6, it should go to the left. Since it's a < symbol, it should be open. Therefore your answer is B.

(looks like you were right!!)

Yuki888 [10]

Answer:

17.3

Step-by-step explanation:

a² = b² + c² - 2bc cos A

t² = 11² + 14² - 2(11)(14) cos 87

t² = 121 + 196 - 308 (.052336)

t² = 300.88

t = 17.3

Solve y=-1/4x+2<br> 2x+8y=-40
PolarNik [594]

Answer:

No solution

Step-by-step explanation:

This is just a simple system of equations.

y=-1/4x+2

8y+2x=-40

Get the same variables onto their corresponding sides, so it will look like this:

y=-1/4x+2

8y=-2x-40

Now here, you have to be careful, because to solve for the system of equations, you need to make sure you are multiplying the equation proportionately.

8y=-2x+16

8y=-2x+40.

But here you see that they share the same variables in a similar format, but their values are supposed to be different, meaning that this equation is a false claim. So you would respond to the question as "no solution.
