A square has 4 right angels and 4 sides with equal angels ;)
Answer:
A
Step-by-step explanation:
(fg)(x) = f(x) × g(x)
= (x - 8)(x² + x - 1)
Each term in the second factor is multiplied by each term in the first factor, that is
x(x² + x - 1) - 8(x² + x - 1) ← distribute both parenthesis
= x³ + x² - x - 8x² - 8x + 8 ← collect like terms
= x³ - 7x² - 9x + 8 → A
There are no restrictions on the domain.
9.286
[To change to mixed number, count the number of digits after the decimal point. There are 3 digits, so the denominator will be 1000]

Then we simplify the fraction
(286 ÷ 2)/(1000÷2) = 143/500
Therefore,

Answer:
The limit of a sum is equal to the sum of the limits.
Step-by-step explanation:
The limits of a constant times a function is equal to the constant times the limit of the function.
Answer:

Step-by-step explanation:
The vertex form of an equation of a parabola y = ax² + bx + c:

(h, k) - vertex

We have the equation:

Substitute:

Finally:
