Currently the denominator is

. If you want to move those up so they sit with the numerator, then what you have to do is make the exponents negative. You make a negative exponent positive by moving it under a 1; undo that process to make the exponents negative. If we do that, then the expression would be
Discount = 28.00 - 22.95 = $5.05
Percent saved = 5.05*100 / 28 = 18.04% <-----
Answer:
2 Units
Step-by-step explanation:
THere may be easier ways to do it, but I would just convert them to rectangular and find the distance between those.
(3, -60) becomes (3cos(-60), 3sin(-60)) = (3/2, -3*sqrt(3)/2)
(-5, 105) becomes (-5cos(105), -5sin(105)) = (5/2, -5sqrt(3)/2)
Now just use the distance formula, or in other words think of the two points as being connected by a horizontal and vertical line to form a right triangle. The idea is to find the hypotenuse of that right triangle.
sqrt((3/2 - 5/2)^2 + (-3sqrt(3)/2 + 5sqrt(3)/2)^2)
sqrt((-2/2)^2 + (2*sqrt(3)/2)^2)
sqrt(1 + 3)
sqrt(4)

-y(4y-3x)-3(4y-3x)
(-y-3)(4y-3x) is the answer
Answer:
<h2>
AC = 36.01</h2>
Step-by-step explanation:
Given ΔABC and ΔADB, since both triangles are right angled triangles then the following are true.
From ΔADB, AB² = AD²+BD²
Given AB = 24 and AD = 16
BD² = AB² - AD²
BD² = 24²-16²
BD² = 576-256
BD² = 320
BD = 
BD = 17.9
from ΔABC, AC² = AB²+BC²
SInce AC = AD+DC and BC² = BD² + DC² (from ΔBDC )we will have;
(AD+DC)² = AB²+ (BD² + DC²)
Given AD = 16, AB = 24 and BD = 17.9, on substituting
(16+DC)² = 24²+17.9²+ DC²
256+32DC+DC² = 24²+17.9²+ DC²
256+32DC = 24²+17.9²
32DC = 24²+17.9² - 256
32DC = 640.41
DC = 
DC = 20.01
Remember that AC = AD+DC
AC = 16+20.01
AC = 36.01
