A polygon is called a convex polygon when no line segments between the points, goes inside. The boundaries of the convex polygon do not go inside and all the vertices are pointed outside away from the center.

The interior angles of a convex polygon are less than 180°. Regularly, a polygon is firmly convex, if each line segment with two nonadjacent vertices of the polygon is strictly internal to the polygon but on its endpoints. Each non-fragment triangle is definitely convex.

If 4x- 7 = 2x, then 2x = ?

Answers

If [tex]4x-7=2x[/tex], then [tex]2x=7[/tex].

Hope this helps.

Answer:

7

Step-by-step explanation:

We solve for x first.

So: 4x - 7 = 2x

Subtract 2x from both sides: 4x - 2x - 7 = 2x - 2x

2x - 7 = 0

Add 7 to both sides: 2x - 7 + 7 = 0 + 7

2x = 7

Divide by 2: [tex]\frac{2x}{2}[/tex] = [tex]\frac{7}{2}[/tex]

x =  [tex]\frac{7}{2}[/tex]

Now, we substitute x for  [tex]\frac{7}{2}[/tex] like this:

2 ( [tex]\frac{7}{2}[/tex]) = 7

The figure has an area of 42 yd? Which equation can be
used to find the value of x?
A 13x + 1 = 42
B 14x = 42
C 15x -1 = 42
D 16x=42

Answers

Answer:

B. 14x = 42

Step-by-step explanation:

The figure is composed of a rectangle and a trapezium

(L*W) + [½(a + b)h] = Area of the figure

Where,

Area = 42

L = 2x

W = 3

a = 3 + 4 = 7

b = 9

h = x

Plug in the values

(2x*3) + [½(7 + 9)x] = 42

6x + [½(16x)] = 42

6x + 8x = 42

14x = 42
