Step-by-step explanation:
Givens
The ratio between white bread and brown bread is 10:3, that is, for every 10 white bread, there are 3 brown bread.
2/3 of white sandwiches are vegetarian.
1/2 of brown sandwiches are vegetarian.
We know that white bread is represented by 10, and brown bread is represents by 3. So, 2/3 of 10 are vegetarians, and 1/2 of 3 are vegetarians. The sum of them is
2/3 of 10 are vegetarians =
1/2 of 3 are vegetarians =
Therefore, 49/6 represents all the sandwiches which are vegetarian.

Answer:
f(x) = x² + 7x + 12
Step-by-step explanation:
Given that the zeros are x = - 3 and x = - 4, then the factors are
(x - (- 3)) and (x - (- 4)), that is (x + 3) and (x + 4)
f(x) is the product of the factors, that is
f(x) = (x + 3)(x + 4) ← expand using FOIL
f(x) = x² + 7x + 12
Example
if n=2
(xyz)^2=(xyz)(xyz)=xxyyzz=x^2y^2z^2
if n=4
(xyz)^4=(xyz)(xyz)(xyz)(xyz)=xxxxyyyyzzzz=x^4y^4z^4
the reason is that multiplication is associative (can move parenthasees around with multiply or add)
