∆= b^2 - 4ac
where b= -2
a=1
c=2
therefore: 2^2 - 4 x 1 x 2
= 4 - 4 x 2
= 4 - 8
= -4
Hey there!
We can factor 10a+6 to get our answer.
Remember factoring as the opposite of the distributive property
(i.e factored would by ab+ac and distributive would be a(b+c)).
We can't have <em>a</em> on the outside, since the second term in our expression doesn't contain an that variable.
We take our greatest common factor, or GCF, so it's factored completely.
We have:
2(5a+3).
Hopefully this helps
Answer:
C & F
Step-by-step explanation:
29 - 13 is 16 and 46 - 21 is 25. Everything else is wrong because the differences are not the correct answers except for C and F. Sorry if this sounds kinda confusing
This is probably wrong so...
I would say C because you multiply 3 x H then 3 x4 I think this is the right answer but I'm not so sure though Hope it helped sort of - Ashlynn
