Answer:
Step-by-step explanation:
let <em>t = </em>total, <em>p = origional price.</em>
tax<em>= p(.09) </em>
t+tax= final price.
Original:
<span>The width and length of a rectangle are consecutive odd integers
</span>so W = x and L = x + 2
<span>If the length is increased by 5 feet, then new L = x + 2 + 5 = x + 7
</span>
A = L x W
60 = (x + 7) x
60 = x^2 + 7x
x^2 + 7x - 60 = 0
(x - 5)(x + 12) = 0
x = 5 and x = -12
From here you have x = W = 5 ft and L = x + 2 = 5 + 2 = 7 feet
Area of original = 5 x 7 = 35
answer
<span>the area of the original rectangle: </span>35 ft^2
Area = (1/2)*base*height
45 = (1/2)*base* 10
45 = base*5
45/5 = base
9 = base
base = 9
The length of the base is 9 units.
I think It's a>-3, maybe.
We have to find on the graph which is f ( - 3 ).
This is the quadratic function which passes through the points: ( - 6, - 3 ), ( 0 , - 3 ) and ( - 3, - 9 ).
Also we can conclude that the point ( - 3, - 9 ) is the minimum value of this function. So : f ( - 3 ) = - 9.
Answer:
A ) - 9.
