Always get rid of denominators first. Multiply both right and left side by 6
-7 (6) = -c (6)/6 + 12(6)
-42 = -c + 72
c = 72 +42
c = 114
rearrange like terms together
42 = 18 - 4x
4x = 18 -42
4x = -24
divide both sides by 4
x = -6
150 x .30 = 45

Given a square ABCD and an equilateral triangle
DPC and given a chart with which
Jim is using to prove that triangle APD is
congruent to triangle BPC.
From the chart, it can be seen that Jim proved that two corresponding sides of both triangles are congruent and that the angle between those two sides for both triangles are also congruent.
Therefore, the justification to complete Jim's proof is "SAS postulate".
Easiest way to do this is to turn them all to decimals
√5= 2.23
2.5= 2.5
√9/4= 1.5
5/3= 1.66
order least to greatest:
1.5
1.66
2.23
2.5
Easy it's c you always match up the labels side to side on the equal signature
