Answer:
0.24
Step-by-step explanation:
0.32 ÷ 4 = 0.08
So, a quarter pound of potatoes costs 0.08.
0.08 x 3 = 0.24
So, three quarter pounds of potatoes (0.75) costs 0.24.
{k^2 + 2k + 1 = 25, k^2 + 2k + 1 = 64}
{k^2 + 2k - 24 = 0, k^2 + 2k - 63 = 0}
{(k - 4)(k + 6) = 0, (k - 7)(k + 9) = 0}
{k = -6, 4, -9, 7)
Therefore, range = {-9, -6, 4, 7)
