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

c.

step-by-step explanation:

substitution for (0,1)

y=x^2+4x+1

1=0^2+4(x)0+1

1=0+4(x)0+1

1=4(x)0+1

1=0+1

1=1

substitution for (-3,-2)

y=x+1

-2=-3+1

-2=-2
