Simplify (-6x^2-2x++1)+(-4x^2+3)

=−10x2−2x+4

Step-by-step explanation:

=−6x2+−2x+1+−4x2+3

=(−6x2+−4x2)+(−2x)+(1+3)

=−10x2+−2x+4

Step-by-step explanation:

2 over 5

step-by-step explanation:

the 2: 3 ratio is the length of the ac segment to the cb segment total length. this implies that the ratio between segment ac length and segment ab length is 2: 5. point c is 2/5 from a to b, so the required fraction is 2/5.
