Answer:
10 and 2
Step-by-step explanation:
f(x)=-(x^2-12x+20)
=-(x-10)(x-2)
f(10)=-(10-10)(10-2)
=-(0)(-8)
=0
f(2)=-(2-10)(2-2)
=-(-8)(0)
=0
Answer:
Step-by-step explanation:
so in the inverse property of addition, the sum will equal 0
mistake is in expression 3.
1/4 + 0.25.......should be 1/4 + (-0.25)
Answer:
Final temperature of the solution is 14°C.
Step-by-step explanation:
Given that,
Initial temperature of the solution,
The change in temperature of the solution,
We need to find the final temperature of the solution.
Change in temperature = Final temperature - initial temperature
So, the final temperature of the solution is 14°C.
Answer:
49
Step-by-step explanation:
with a square all sides are equal so if one side is 7 the other is 7 so you would do 7 * 7
hope this helps
Since x represents the length (in meters), the width, which is 7 meters greater, is x +7. The product of these dimensions is the area (in square meters):
x(x +7) = 170
In standard form, the quadratic is ...
x² +7x -170 = 0
