This value of "a" is exactly the y-coordinate of the vertex of the parabola
y = x%5E2+%2B+4x++-+31.
To find it, complete the square:
x%5E2+%2B+4x++-+31 = %28x%2B2%29%5E2+-+4+-+31 = %28x%2B2%29%5E2+-+35.
So, this value of "a" is a = -35.
Figure. Plot y = x%5E2+%2B+4x++-+31.
To compare two fraction you need to rewrite the fractions so they have a common denominator.

D. The fraction 1/2 should have been rewritten as 4/8.
I believe the volume of one rubber ball is 20.58780
Answer: The sum of the lengths of any two sides of a triangle must be greater than the length of the third side. Since, 11 + 21 > 16, 11 + 16 > 21, and 16 + 21 > 11, you can form a triangle with side lengths 11 mm, 21 mm, and 16 mm.
Step-by-step explanation:
Answer:
1: $1.50
2: $3.00
4: $6.00
5: $7.50
6: $9.00
7: $10.50
8: $12.00
9: $13.50
Step-by-step explanation: To answer this problem you need to divide $4.50 by 3. When you do that you get $1.50 per pound of gummy bears. Then you can either add $1.50 to each amount or multiple them by the x value. Then graph the numbers you get.
