Let’s write it simply, that helps us solve it easier.
6x^2+4x+8
Now, insert 7 in place of x.
6(7)^2+4(7)+8
Now, multiply.
42^2+28+8
Solve for exponents.
1,764+28+8
Add.
1,792+8
1,800
Hope this helps!

Instructions: Use the ratio of a 30-60-90 triangle to solve for the variables.

Pepsi [2]

Answer:

$x=20$

$y=10\,\sqrt{3}$

Step-by-step explanation:

In the triangle we have the following trigonometric equations:

$tan(60^o)=\frac{opposite}{adjacent} \\\sqrt{3} =\frac{y}{10} \\y=10\,\sqrt{3}$

and also:

$cos(60^o)=\frac{adjacent}{hypotenuse}\\\frac{1}{2} =\frac{10}{x}\\x=20$

Which of the following statements are correct? Select all that apply.

Marizza181 [45]

For a 7 sides polygon which is called heptagon or septagon
Interior angles = (7-2)*180/7 = 128.57°
Exterior angle = 180 - 128.57 = 51.43°
Central angle = 360/7 = 51.43°

The statements which are correct:

3. The regular polygon ABCDEFG can be broken down into 2 isosceles trapezoids and 1 isosceles triangle

5. The central angle of the polygon ABCDEFG is about 51.43° and each interior angle is about 128.57°

7. The central angle ABCDEFG is the same measure of the exterior angle
