Let assume x be the sale price
A clothing store advertises that it is having a 25% off sale.
The sale price with 25% discount is f(x) = sale price - 25% of sale price
f(x)= x - 0.25x = 0.75x
For one day only, the store advertises and additional savings of 10%.
The sale price with 10% discount is g(x) = sale price - 10% of sale price
g(x)= x - 0.10x = 0.90x
Use composition function
g(f(x)) = g( 0.75x) = 0.90(0.75x) = 0.675x
That is 0.675/100 = 67.5%
The total percent discount = 100% - 67.5% = 32.5%
what would be the sale price of a $40 sweater?
Here sale price x= 40
So we plug in 40 for x
g(f(40)) = g( 0.75(40)) = 0.90(0.75(40)) = 0.675(40) = 27
The sale price of sweater = $27

Since we've established before that a square can be a rhombus or a
parallelogram, the criteria that two adjacent angles must be equal holds
for both. This shape can be a trapezoid in the special case where one
pair of sides is congruent and parallel and the other is congruent but
creates a shape such that opposite angles are supplementary and adjacent
angles are congruent.
1/3 of 154.35 is 51.45
$51.45 will be saved on the jacket with it's regular price.
154.35 - 51.45 = 102.90
The sale price of the jacket will be 102.90 .
Hope I was able to help!
C=√a²+b. square both sides
c²=a²+b². subtract a² from both sides
c²-a² = b². take the square root of both sides
b=±√c²-a²
but since length can never be negative we consider only the positive root
b=√c²- a²
12. 56 + 12 = 4n
68 = 4n
68/4 = n
17 = n...its A
13. 4x - 2 = -18 + 6x
-2 + 18 = 6x - 4x
16 = 2x
16/2 = x
8 = x
