You need to cut the shape into other shapes that you know the formula off
You know the total length ST and SU, so to find x you would write an equation. This would be: x+4+2x=16 Combine like terms: 3x+4=16 Subtract four from both sides: 3x=12 Divide both sides by three: x=4
Answer:
C = -6
Step-by-step explanation:
C = [2×1/4 + 1] ÷ [3×1/4 -1 ]
C = 3/2 ÷ -1/4
C = 3/2 × -4 = -6
C = 2d + 1 / 3d - 1
So, d = ( C + 1 ) / ( 3C - 2 )
If you would have to graph x=7, you probably know that this is a vertical line at, well, x=7.
| x | = 7 is nothing more than two vertical lines, namely x=7 or x=-7, as you already wrote down.
| x | = -8 has no (real) solutions, so there is nothing to graph.
