Answer:
28408
Step-by-step explanation:
212x134=28408
For question 4, it would be a^2+b^2=c^2. So you would set up the equation as a^2+14^2=18^2. the third side would equal approximately 23cm.
-10x-1 = 11 -9x
+10x +10x
-1 = 11 + x
-11 -11
-12 = x
x= -12
She will need to cut 26.6 haircuts a month a location A to break even (1200/45 = 26.6) so roughly 27 haircuts to make a profit
She will need to cut 30 haircuts at location B to break even (1800/60 = 30) and 31 hair cuts to see a profit.
She will need to cut 30.67 haircuts at location A and 33 haircuts at location B to make the same profit at either location (Roughly $180).
30.67 x 45 = 1380.15 - 1200 = 180
33 x 60 = 1980 - 1800 = 180
The is answer E, you have to search for -3 in the x line than search for -2 in the y line
