X2+7x-8=0
product=-8 times 1 = -8
sum= 7
{-1, 8}
x2-1x+8x-8=0
x(x-1)+8(x-1)=0
x+8=0 or X-1=0
x=-8
I think its C... but to be honest, I have no idea. Im so sorry, but I hope this helps
Answer:
the answer is 2.5
Step-by-step explanation:
add 4+3+2+1=10
add 2+1+8+10+4=25
divide 25÷10= 2.5
So we have to work out the price of 1 for each.
20 divided by 23 is 0.8696
12 divided by 15 is 0.8.
So Bob has a better sale as you can get more cans for cheaper if you work out one
