Answer:
A. 15x^3 -44x^2 +9x +28
Step-by-step explanation:
(5x^2 -3x -4)(3x - 7)
first, distribute by multiplying the terms in each parenthesis with each other:
(5x^2 * 3x) - (3x * 3x) - (4 * 3x) - (5x^2 * 7) + (3x * 7) + (4 * 7)
simplify:
15x^3 -35x^2 -9x^2 +21x -12x +28
Now combine like terms:
15x^3 -44x^2 +9x +28
Answer: There are 32 candles in the small box.
Step-by-step explanation:
Since we have given that
Size of small box= 2 ounces
Size of large box = 6 ounces
Number of candles in large box = 96,
We need to find the number of candles in the small box ,
As there is direct variation between the small box and large box ,
let the number of candles in the small box be x
So,

so, there are 32 candles in the small box.
Answer:
7x
Step-by-step explanation:

Solution (1)



for k=0 / for k=1 / for k=-1
x=0 / x=2π / x=-2π
acc / acc / rej
solution (2)




for k=0 / for k=1 / for k=-1
x=0 / x=2π/3 / x=-2π/3
acc / acc / rej
Note that i'm trying values of K which make the answer belong to our interval;
So our solution which i will represent as a set is;
S € {0,2π/3,2π}
