(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

its kind of blurry. can you put a clearer pic?

step-by-step explanation:

38.6°

step-by-step explanation:

resultant is 10 pound

smaller force = 8 pound

angle formed = tan⁻¹(

                        =tan⁻¹(

                          =tan⁻¹(0.8)

                        =38.6°
