Answer:
We have the equation:
(ax^2 + 3x + 2b) - (5x^2+bx-3c)= 3x^2 - 9
First, move all to the left side.
(ax^2 + 3x + 2b) - (5x^2+bx-3c) - 3x^2 + 9 = 0
Now let's group togheter terms with the same power of x.
(a - 5 - 3)*x^2 + (3 - b)*x + (2b + 3c + 9) = 0.
This must be zero for all the values of x, then the things inside each parenthesis must be zero.
1)
a - 5 - 3 = 0
a = 3 + 5 = 8.
2)
3 - b = 0
b = 3.
3)
2b + 3c + 9 = 0
2*3 + 3c + 9 = 0
3c = -6 - 9 = -15
c = -15/3 = -5
Then we have:
a = 8, b = 3, c = -5
a + b + c = 8 + 3 - 5 = 6
D=√(6-0)²+(2-10)²
d=√(6)²+(-8)²
d=√36+64
d=√100
d=10
Answer:
10 lemons
Step-by-step explanation:
This is easy proportions.
What you do
is that you find the unit rate
or you can do it my way
which is a ton easier
which other people do
so anyways
you know 2 lemons for every 7 cups of lemonade
so you know you want 35 cups of lemonade
so you can multiply 7 by 5 to get 35
so you multiply 5 by 2 lemons to get 10 lemons
2/7 = x/35
In standard notation it would be, 758*10^6
