Evaluate the following algebraic expression at a -3 and simplify your answer
2(a-4)-4(a+3)

-26

Step-by-step explanation:

first, simplify the equation

2(a - 4) -4(a + 3)

distribute

2a -8 -4a -12

combine like terms

-2a - 20

now plug in a =3

-2 (3) -20

simplify by distributing then solving

-6 -20

= -26

its 50 miles away from the starting point

1 + (6 / x - 1)

step-by-step explanation:

divide using polynomial division.
