three different forms: standard, intercept and vertex
Answer:
The answer is 175.5.
Step-by-step explanation:
This is because 25% of $260 is $65. Then you must subtract that from the original price. $260 - $65 = $195. Then, it says '10% off the sale price'. The sale price is $195. 10% of this is 19.5. Finally, you subtract this from the $195, with a final amount of $175.50

Answer:
x = 7
Step-by-step explanation:
from the properties of an isosceles triangle, 5x+6 = y-9
so
98+2(5x+6) = 180
98+10x+12 = 180
110+10x = 180
10x = 70
x = 7
Let width = x
Let length = 2x + 11
Area = 63 ft2
length × width = Area
x(2x + 11) = 63
2x2 + 11x = 63
Subtract 63 on both sides of equation.
2x2 + 11x - 63 = 0
Factor the left side of equation.
(2x - 7)(x + 9) = 0
x = 7/2 and x = -9
Since the dimensions cannot be negative, we accept the positive value of x: x=7/2. Substitute this value of x into the dimensions
width = 3.5 ft
length = 2(3.5) + 11 = 7 + 11 = 18 ft
