Answer:
0 true for all values
Step-by-step explanation:
Answer:
B. (b x d) - c
Step-by-step explanation:
i. -(a x d) + b
= -(6 x 
) + 8
= -3 + 8
= 5
ii. (b x d) - c
(8 x ) - 4
= 4 - 4
= 0
iii. 2(b x f) + a
= 2(8 x 
) + 6
= 4 + 6
= 10
iv. (a x e) - c
= (6 x 
) - 4
= 2 - 4
= -2
Thus, the expression which is equivalent to 0 is that of option B.
Hello :
<span>x²+2x+y²−4y+z²−8z=60
(x²+2x) + (y² - 4y) +(z² - 8z) = 60
(x²+2x+1) -1 +(y² - 4y +4 ) - 4 +( z² - 8z+16) -16 = 60
(x+1)² +(y-2)² +(z - 4)² = 9²

Answer:
he is 23 miles northeast from this starting spot
Step-by-step explanation:
ok so you start with the directions and notice they are different but this equation worked in our favor because the directions are north and east then all you do is add 8 + 15 and you get 23 so its 23 miles northeast from starting position
