Answer:
17 + 23 = 40
23 - 17 = 6 the other person did it right.
Rewrite it as 5x^2 -20x-3x+12
then (5x^2 -20x)(-3x+12)
then use gcf and u will get the answer in a binomial form
A) 500 ml
b) 8.5 km
c) 480 cm
d) 9000 g
e) 550 mm
If you add positive 5 and positive 5, you'll get positive 10.
If you add positive 5 and negative 5, you'll get positive 0.
If you add negative 5 and negative 5, you'll get negative 10.
-5 + 5 = -5 + 5
5 + 5 = 5 + 5
- 5 + -5 = -5 + -5
Does that help your question?
