if A= xy +x+-2, find the value of A for x=-4 and y=5.
if B = 3x - 2y +1, find the value of B for x = 8 and y=2.
8.​

Answer 1

Step-by-step explanation:

in first part you should put the value of

x and y then multiplied them and -4 and -2

so the equation will be

A=-4×5+(-4)+(-2)

A=-20+(-8)

A=-28

B=3x-2y+1

B=3×8-2×2+1

B=24-4+1

B=21

hope it helps you☺️
