He has 36 tomatoes left. Since he had 72 tomatoes in the beginning but gave away 21 to his neighbor and 15 to his brother, you have to subtract those two values from 72. The equation would be 72-21-15 which results in 36. Therefore, Antonio has 36 tomatoes left.
A polynomial where the ends are facing downwards is an even-degree polynomial with a negative leading coefficient.
An example for this is : f(x) = -x^2
where the degree is even (2) and the leading coefficient is negative (-1).
When graphing this function, you'll find both ends pointing downwards.
Answer:
x = -8, x = -4
Step-by-step explanation:
Adding a number and its opposite gives a result of 0. That is, x+8 will be 0 when x = -8, because -8 +8 = 0.
Likewise, x+4 will be zero when x = -4, because -4 +4 = 0.
The values of x that make (x+8)(x+4) = 0 are -8 and -4.
