8 people take up one table and 104/13=8
Question 4 is Choice A
Question 5 is Choice B
Question 6 is Choice C
Question 7 is Choice B
These are relatively simple it’s just understanding the relations of x and y values :)
The domain is actually the x value of the function, so we need to find the value of x
suppose the width is x, the length is then 3x+5
the area is 50^2 inches, so x(3x+5)=50 => 3x^2+5x-50=0
Factor this quadratic equation: (x-5)(3x+10)=0 =>x=5 or x=-10/3
width can not be negative, so the width is 5
the domain is x=5
Answer:
144.
The reason is because 1 ft = 12 in, (1 ft)2 = (12 in)2 = 144 in2.
10 times the sum of 2 and 1 is represented by the following expression:
10 x (2 + 1)
10 x is ten times, and (2 + 1) the sum of 2 and 1, "10 times the sum of 2 and 1".
