Answer:
153 points
Step-by-step explanation:
Set up a proportion:
34/4 = x/18.
18/4 does not equal a whole number. So, reduce 34/4.
34/4 becomes (when divided by 2 on both the top and the bottom) 17/2.
18/2=9. 9*17=153.
A function with zeroes at z1 and z2 can be factored into form
f(x)=a(x-z1)(x-z2)
where a is a constant
so
it is
f(x)=a(x-(-4))(x-2) or
f(x)=a(x+4)(x-2)
2(6x+20) +2(8x-16)=180
12x+16x+40-32=180
28x+8=180
X=180-8/28=6
I think so my calculation may be wrong )
