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
All 3 use a similar equation to find the area
A=bh for <span>parallelograms and rectangles
and A=1/2bh for triangles.
plus a rectangle is a parallelogram with all angles at 90 degrees and a parallelogram can be made up of triangles</span>
1) substitute 10x in for the equation.
Answer: 3x -4
Step-by-step explanation:
The LCM of 4 and 14 would be 28, all you have to do is put all multiples of both numbers and find the FIRST common one. So like this:
4, 8, 12, 16, 20, 24, 28
14, 28
So basically in small terms all u do is find the first multiple that BOTH numbers have and it has to be the same.
