Answer:
1. last choice
2. first choice
Step-by-step explanation:
<h3><u>First</u><u> </u><u>Image</u></h3>
The reason why it is the last choice because when times keep going as distance also keeps increasing as well. But the last choice says that run at the end of track then turn around and run back. That means there must be a decreasing distance and a maximum value as well.
Therefore the only with max point/vertex is the absolute value which matches the last choice.
<h3><u>Second</u><u> </u><u>Image</u></h3>
First choice because the car straight forwards without any change. The car runs with a steady speed but the distance will keep changing without any change of distance.
So the answer is first choice.

Let
x-------------> amount added <span>to each side
</span>A-------------> area increased----------> 84 ft²
we know that
A=(10+x)*(5+x)=84-----------> 10*5+10*x+5*x+x²
50+15x+x²=84----------> x²+15x-34=0
<span>solving the second order equation
</span>x1=-17
x2=2
the answer is x=2 ft
19÷4=4.75
To make it into a percentage, multiply it by 100
4.75×100%=475%
If there are 27 students in the class and they have to form as many groups of 4 as possible, you can calculate this using the following step:
27 / 4 = 6.75 = 6 3/4
Result: 27 students can form 6 groups of 4 students and 3 students have to form their own group.
