Answer:
Step-by-step explanation:
The given quadratic equation is:
Comparing it with the standard form of Quadratic Equation 
, we get:
a = 3, b = -9 and c = 1
Discriminant = b² - 4ac
D = (-9)²-4(3)(1)
D = 81 - 12
D = 69
30%÷100% = 0.30; $85×0.30= $25.50; 85 - 25.50= $59.50.
15%÷100% = 0.15; $59.5 ×0.15 =8.92; 59.50 - 8.92= $50.58
$50.58
Guessing that the 3 was suppose to be an exponent.
The answer written in standard form is :
4x^3 + 10x - 4
This is called a cubic trinomial.
Answer:
24 monkeys are in the tree
Step-by-step explanation:
We solve it by writing 
times 
Why is it over 100? Because every percent is out of 100!
X (your equation)
60 times 40 = 2400 and 100 times 1 = 100, We get, 
,
Lastly, we simplify the fraction by 100 on each side:
/ 
you get 24
Answer:
4w + 9
Step-by-step explanation:
Area of rectangle = length x width (or base x height, depending on how you look at it).
It is given to you that:
Area = 8w + 18
Length = 2
Let: width = x
Plug in the corresponding terms with the corresponding words:
8w + 18 = 2x
Isolate the variable, x. Divide 2 from both sides of the equation:
(8w + 18)/2 = (2x)/2
x = (8w + 18)/2
w = (8w)/2 + (18)/2
w = 4w + 9
4w + 9 is the expression that represents the width of the rectangle.
