i think it 30 but I could be wrong
Answer:
4
Step-by-step explanation:
I assume that is supposed to be x squared. A perfect trinomial is the product of a perfect square, (x times a number) squared. With these trinomials, you can look at them as: ax squared times bx + c. When a is 1, the fastest way to get c to make a perfect square is to divide b by 2. In this case, it's 4/2 = 2. The last step is to square that number. 2 squared = 4.
Answer:

and there is really no solution
Answer:
the amount the stock changed over the day = $29
Step-by-step explanation:
The stock cost $122 at the start of the day . At the end of the day it cost $93. The amount the stock value changed can be calculated below.
The initial amount of the stock that days was $122 but at the end of the day it changes to $93. This means the stock cost decreases over the day.
Initial cost of stock at the day = $122
Final cost at the end of the day = $93
the amount the stock changes over the day = initial cost of stock at the day - final cost at the end of the day.
the amount the stock changes over the day = 122 - 93
the amount the stock changed over the day = $29
Generally, the stock decreased over the day.
Answer:
4 inches
Step-by-step explanation:
40/24=10/6
40/10=4
24/6=4
(40/24)/(4/4)=10/6
(10/6)(4/4)=10/24
