One plane flies across the country with a path modeled on a map by the equation 2x−7y=−25. Select all the equations for lines that could represent perpendicular flight paths.
A. y=27x−6
B. 7x+2y=−10
C. y−13=72(x+8)
D. 14x+4y=41
E. 7y=2x+5

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

your answer is b.

x = 33.9

y = 65.6

step-by-step explanation:

86

step-by-step explanation:

find the area of the triangle then multiply by 2 then add the area of the parollelegram multiplied by 2

answer: the answer for that is 22/3
