15 points!! m ABC + mBAC + m ACB
when ABC is an isosceles triangle with AB=AC
mABC when mBAC = 70°
and ABC is an isosceles triangle with
AB=AC
mZQPR when mZQRP = 30°
and APQR is an isosceles triangle with
PQ = QR
mZBDE when mZBAC = 45°
and points D and E are the midpoints
AB and BC, respectively, in AABC

f(x) = x^3 -2x^2 -3x

x( x^2 -2x-3)

x( x^2 +x -3x -3)

x( x(x+1) -3(x+1))

x( x-3)( x+1)

so zeroes are 0, 3,-1

its (2) option

question 1 is 8, question 2 is 9, question 3 is 24

step-by-step explanation:

now, the numbers they give you at the top are the key. from there, you just have to plug and chug! let's try 1, 2, and 3!

key: a=3, b=5, c=6

1. a+5

remember, a=3, so we plug that in to get 3+5=8

2. 15-c

c=6, so we plug that in to get 15-6=9

3. 4b

b=6, so we plug it in to get 4*6=24

time to try the rest on your own! if you put the answers below in a comment, i'll check them for you!
