Start by writing a formula, where 
is Brad's purchase price and 
is the original price.
Subtract 
from both sides.
Multiply both sides by 
.
It would be (all under a big square root) (-7-5)squared + (3+2) squared. This equals to about root 169
Let’s says that x is the measure of the angle. X and it’s supplement are equal to 180. X and it’s complement are equal to 90. The supplement is s and the complement is c. S is times c which is the same as 3c.
3c + x = 180
C+x = 90
X = 90 - c
3c + 90 - c = 180
2c = 90
C = 45
The complement of. 45 degree angle is 45 degrees.
The angle is 45 degrees.
Answer:
<em>A) 84x-16y-10.6</em>
2(14x-3y+28x+12.2-5y-17.5)
2(48x-3y+12.2-5y-17.5)
2(48x-8y+12.2-17.5)
2(48x-8y-5.3)
<em>84x-16y-10.6</em>
