The correct answer is y= x^2-16
Answer:
-2b/(a-b)
Step-by-step explanation:
1− (a+b/a−b)
We need to get a common denominator of a-b
1 = (a-b)/(a-b)
Replace 1 with (a-b)/(a-b)
(a-b)/(a-b) - (a+b)/(a-b)
Put over the common denominator
(a-b) - (a+b)
-----------------
(a-b)
Distribute the minus sign.
(a-b) - a-b)
-----------------
(a-b)
a-a-b-b
---------------
a-b
-2b
----------
a-b
Answer:
Don't worry I will help to solve this problem OK.Sorry I don't understand please ask with other OK .
Step-by-step explanation:
base = 40
height = 16
Area of parallelogram = b×h = 40× 16= 640
Answer:
6
Step by step explanation:
2 + 2 * x = 10
2x+2=10
2x+2−2=10−2
Therefore, x = 6
Answer:
130m
Explanation:
So your whole area would be 1000m^2
Long as: 15 + x
Wide as : x
We know x(x+15)=1000
x^2+15x-1000=0
Delta: 225+4000=4225
x=-15+-65/2
x= 25 and x=-40
As it is a measurement, we discard the negative measurement.
Now it is 25m wide and 40 long.
Multiply by two each to use both sides:
50+80= 130m
Hope you get it!
