Determine the value of x in this polygon.

Mathematics
1 answer:
OLEGan [10]2 years ago
3 0

Answer:

<h2>x = 23.5</h2>

Step-by-step explanation:

It's the trapezoid.

We know: the sum of the angle measures at one leg of a trapezoid is 180°.

Therefore we have the equation:

(x+12.5)+(6x+3)=180    <em>combine like terms</em>

(x+6x)+(12.5+3)=180

7x+15.5=180         <em>subtract 15.5 from both sides</em>

7x=164.5   <em>divide both sides by 7</em>

x=23.5

olchik [2.2K]

Answer:

10 visors

Step-by-step explanation:

Make an equation

Each visor, v costs $6, and there is a $5 fee regardless of the amount of visors purchased. This must be equal to $65

6v+5=65

Now, solve for v

Subtract 5 from both sides

6v=60

Divide both sides by 6

v=10

You can buy 10 visors

Graph the function y = x3 + 6x2 + 2x – 11. Based on the graph, what is the largest possible x-value if y = 0?
professor190 [17]

Answer:

Step-by-step explanation:

The graph is done using Desmos. Just by substitution x = 1 will force the graph to go to y = 0, but graphs are not always that good. This one gets 1.111

to get y = 0. I'd use 1 if you had to answer it and a computer will mark it.
