Sara is working on a Geometry problem in her Algebra class. The problem requires Sara to use the two quadrilaterals below to ans
wer a list of questions. Part A: For what one value of x are the perimeters of the quadrilaterals the same? (Hint: The perimeter of a quadrilateral is the sum of its sides.)
Part B: For what one value of x are the areas of the quadrilaterals the same? (Hint: The area of a quadrilateral is the product of its base and height.)
For part A I think that the sides are the same because if both of the x+4's just add the 4's to each other and then you may get X. For Part B I believe that if you're adding still then you may still get the same number on both sides.
First turn the statement into an equation:
3X=12+(X+26). You can combine the 12+26 and now you should have 3X=X+38. Subtract an X from both sides of the equation (2X=38) now finally divide by 2 to find X. X=19
If there are 40 kids and 22 of them play soccer that leaves you to subtract 22 from 40 which gives you 18. After that, you put the rest of the 18 students over a total of 40 and divide to get the decimal .45 and if you convert that into a percent you are left with 45%.
