Answer:
x = 19
Step-by-step explanation:
Solve for x:
3 x + 43 = 100
Subtract 43 from both sides:
3 x + (43 - 43) = 100 - 43
43 - 43 = 0:
3 x = 100 - 43
100 - 43 = 57:
3 x = 57
Divide both sides of 3 x = 57 by 3:
(3 x)/3 = 57/3
3/3 = 1:
x = 57/3
The gcd of 57 and 3 is 3, so 57/3 = (3×19)/(3×1) = 3/3×19 = 19:
Answer: x = 19
We know that
the area of the shaded regions is equal to
area of the shaded region 1+area of the shaded region 2
step 1
find the area of the shaded region 1
area of the shaded region 1=Area regular Hexagon-Area <span>regular Pentagon
step 2
</span>find the area of the shaded region 2
area of the shaded region 2=Area of a square-Area of the <span>equilateral triangle
</span>
therefore
the area of the shaded regions is equal to
[Area regular Hexagon-Area regular Pentagon]+[Area of a square-Area of the equilateral triangle]
