Answer:
(i) = 3
(ii) = 20
Step-by-step explanation:
x = 1
y = -2
z = -1
(i) 4x - 3y + 7z
4(1) - 3(-2) + 7(-1)
4 + 6 - 7 = 3
(ii) 2x³ - 6y²z + 3xyz²
2(1)³ - 6(-2)²(-1) + 3(1)(-2)(-1)²
2 + 24 - 6 = 20
A represents it, since it’s on the negative side

In order to determine the distance he can run in 1 3/4 hour, we can write;
Cross multiply to have:
x * 1 = 7/4 * 34/5
x = 238/20
X = 11.9miles
Hence Zoe will have to run 11.9 miles
