15 What is the equation of a circle that has a diameter with endpoints located at points (4,2) and (-4,8)?
A) 22 + (y – 5)2 = 25
B) (2 + 4)2 + (y - 8)? = 25
C) (- 5)2 + y2 = 25
D) (2 – 4)2 + (y - 2)2 = 25

a

step-by-step explanation:

if farmer matt works for 8 hours a day, how many days will it take him to completely plant 12 rows of crops? each batch of cookies needs 3/4 cups of sugar.

step-by-step explanation:

the polynomial is a perfect square trinomial of the form a^2-2ab+b^2:

option a. true

step-by-step explanation:

9x^2-12x+4

comparing with the form a^2-2ab+b^2

1.) a^2=9x^2

solving for a: square root both sides of the equation:

sqrt(a^2)=sqrt(9x^2)

a=sqrt(9) sqrt(x^2)

a=3x

2.) b^2=4

solving for b: square root both sides of the equation:

sqrt(b^2)=sqrt(4)

b=2

to be a perfet square trinomial 2ab must be equal to 12x. let's check:

2ab = 2 (3x) (2)

2ab = 12x

correct

d will be the best answer
