X^2 - 14 x = 15
(x - 7)^2 - 49 = 15
(x-7)^2 = 64
x - 7 = - or + 8
x = 15 or -1
Just take half o the coefficient of x and subtract it squared as above.
In general
x^2 + ax = b
(x + a/2)^2 - a^2/4 = b
Answer:
4/6
Step-by-step explanation:
for y=x-7+1 the domain is all real numbers
for any x input, you will get a y output.

Answer:
24
Step-by-step explanation:
area of circle = πr²
πr² = 144π
Cancel out π
r² = 144
r = √144
r = 12
diameter = 2 x radius
diameter = 2 x 12
diameter = 24m
* diameter is the "width of a circle", the distance from the widest points of the circle
