(Simplify the expression and find its value when a = 5 and b = -3)
2(a^2+ab)+3-ab

38

Step-by-step explanation:

2(a^2+ab) + 3 - ab

=  2a^2+ 2ab + 3 - ab

= 2a^2 + ab + 3

= 2x5^2 + 5x(-3) + 3

= 50 - 15 + 3 = 38

im alright what do you need

step-by-step explanation:

the answer is d

the answer is in the first quadrant, which make the y-int positive.

since the dots are going down, therefore the correlation is negative

i hope it is right.
