Answer:

x = 13

Step-by-step explanation:

10 + 5x -4(x - 2) = 31

10 + 5x - 4x + 8 = 31

10 + 8 + 5x - 4x = 31

18 + 1x = 31

-18          -18

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

1x = 13

/1     /1

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

x = 13

What is the solution of the inequality<br> -6x-17greater or equal to 8x+25
Masja [62]
-6x -17 ≥ 8x + 25

Subtract 8x from each side:

-14x -17 ≥ 25

Add 17 to each side:

-14x ≥ 42

Divide each side by 14 :

-x ≥ 3

Change the signs. (Multiply each side by -1.)
That's when you have to flip the inequality symbol.

x ≤ -3

If we join the Center with different corners of the polygon,we find 10 Isoceles triangle with equal side=9.14cm, Making an angle of 36° between the equal sides.

Area of 1 triangle= a*b*sinC/2
= 9.14*9.14*Sin36°/2
= 9.14*9.14*0.587/2
=24.51 cm^2

Area of 10 triangle= 24.51*10
= 245.1cm^2
