Let a and b be the numbers,then a+b=32,b=32-a
ab=-320
a(32-a)=-320
32a-a^2=-320
a^2-32a-320=0
a^2-40a+8a-320=0
a(a-40)+8(a-40)=0
(a-40)(a+8)=0
a=40 or-8
when a=40,b=32-40=-8
when a=-8,b=32-(-8)=32+8=40
so numbers are 40 and -8
Answer:

Hello,
We may suppose that abscisse of C is 21 or 22
As √484=22
Answer D:
Answer:
x=1.25
Step-by-step explanation:
Let us replace the number with the variable "x". You will then get this equation:
8x-2=8
Move the -2 to 8 and you would get the equation:
8x=8+2
Simplify:
8x=10
Simplify:
x=10/8
You would then get the answer "x=1.25"
I hope this helps :)
