Answer:
$5.10
Step-by-step explanation:
The owner buys 5 panes of glass for $12.75. So to find the cost of 1, we need to divide the total cost by the amount of planes. In this case, 12.75 divided by 5. This gives you $2.55 per plane. And since he is buying 2 more, we would multiply the cost of the plane (2.55) by the amount we are buying (2). So we do 2.55 X 2 and we get $5.10
Answer:
C
Step-by-step explanation:
8i
√-64 = i√64 = 8i
Square root of 64 is 8. 8x8=64
cube root of 64 is 4. 4x4x4=64
It's the smallest value in this equation which should at x=-10, the equation is x=-b/(2a)
