What is the correct length of the side Bc? Round to the nearest tenth and only type in one number.

Step-by-step explanation:

I would suspect you want to know what's wrong with the work.

AC is the hypotenuse. c = AC.

It should be done this way.

c = 6 in

b = 15 in

a = ?

a^2 + c^2 = b^2

a^2 + 6^2 = 15^2

a^2 + 36 = 225

a^2 = 225 - 36

a^2 =  189    

sqrt(a^2) = sqrt(189)

a = 13.75

it's d.

step-by-step explanation:

because: -1(4x + 1y) +2 (1x-3y) distribute each number into the parenthesis.

then you would get: -4x - 1y + 2x -6y combine like terms

and get: 2x -7y

hope my answer has you if not then i'm sorry.
