Answer:
141, meaning that there will be two real solutions
Step-by-step explanation:
The discriminant of a quadratic is
, which in this case is:

Since the discriminant is positive and not zero, there will be two real solutions to this equation. This is because when the discriminant is negative, and you take the square root of it, you get a negative number. If you take the square root of 0, you get 0, which means that there will only be one solution to the equation.
Hope this helps!
Answer:
The answer is 9x-4.
Step-by-step explanation:
First calculate the area of the backyard. This is 13x-1. Then multiply the area of the patio so multiply x +3 by x+ 3. The answer to this is 4x+3. Next subtract the area of the patio from the area of the backyard. The answer is 9x-4.
Answer:
The average number of machine cycles per instruction for this microprocessor is 5.8.
Step-by-step explanation:
To find the average number of machine cycles per instruction for this microprocessor, we multiply each number of cycles for it's relative frequency.
We have that:
25% require 2 cycles.
20% require 3 cycles.
17.5% require 4 cycles.
12.5% require 8 cycles.
25% require 12 cycles.
So the average number is:

The answer is that he spent 33 1/3% (A) on chicken.
Because the money he spent on chicken and burgers in total is 135. The money he spent on chicken to the money in total is : 45/135. Simplified it would be 33.333%
