Answer:
Step-by-step explanation:
A third degree polynomial has a <em>total of three roots</em>, real and imaginary combined.
If it already has 2 real roots, -4 and +4, then it has to have three real roots because imaginary roots come in conjugate pairs, i.e. they come in even numbers.
Julie wants to buy cartons of apple juice with $55. Each carton costs $3.75.
Let x be the number of cartons she can buy.
3.75x =< 55
Divide both sides by 3.75
3.75x / 3.75 =< 55/3.75
x =< 14.66666
Of course, she can't buy 14.666 cartons so we can the integer part only. Julie can buy 14 cartons of Juice.
Hope this helps! :D
Answer:
6 inches.
Step-by-step explanation:
Let a represent side length of larger square.
We know that area of square is square of its side length, so area of the larger square will be
.
The area of smaller square would be
.
We will use proportions to solve our given problem.



Cross multiply:



Take square root:


Since the length cannot be negative, therefore, the side length of larger square is 6 inches.
