Answer:
n= -3 and n= -6
Step-by-step explanation:
We need to solve this equation to find the value of n.
Rearranging:
This is a quadratic equation and we can solve by using factorization method.
We need to make factors of 18n^2 such that their sum is equal to 9n.
So solving,
Neutrons= Atomic Mass Number- Atomic Mass Number
So 85-25= 60
Answer:
You can make 10 tortillas with one and a half kilograms of ground meat
Step-by-step explanation:
one and a half kilograms to grams
1.5kg x 1000 = 1500g
150 grams prepared to make 1 hamburger
than, 150 x h = 1500
h = 1500 / 150
h = 10
Answer:
Step-by-step explanation:
p(x) has degree 3
(x - 4) has degree 1
So p(x) can be rewritten as a polynomial of degree 2 multiplying (x-4)
So
To find a, b and c, we have to divide p(x) by x - 4.
So
Finding a:
Dividing the first term of p(x) by x - 4.
So a = 3.
Now multiplying 3x² by, x - 4, we have:
Subtracting p(x) from this:
Finding b:
Dividing the first term, after the subtraction, by x - 4.
So b = -8.
Multiplying -8x by x - 4, we have:
Then
Finding c:
So c = 5.
Just to verify if the remainder is 0.
Ok
