The diameter of a regulation soccer ball is about 8 and three-fifths inches. This number was graphed on a number line. A number line going from negative 9 to positive 9. Point A is between negative 9 and negative 8, point B is between negative 7 and negative 6, point C is between 6 and 7, point D is between 8 and 9.

Which point could be the point representing the graph of the diameter of the ball?
A
B
C
D

according to egenuity the answer is

step-by-step explanation:

d. 344.22

x² + 3x + 7 = 0       [ax² + bx + c]

a = 1

b = 3

c = 7

quadratic formula:

    (+/- is this ±)

plug in the numbers into the variables

your answer is a

96 39 cause 135 -96=39 im smart (i used a calculater)

hello from mrbilldoesmath!

answer:   x (x+6)^2, choice b

discussion:

factor x out of the equation:

x^3 + 12x^2 + 36x = x (x^2 + 12x + 36).

note that 6+6 = 12 and 6*6 = 36 so the above factors into:

x (x+6)^2

which is choice b
