Answer: $265
Step-by-step explanation: I just added all the numbers together.
First, divide the total cost by the unit cost:
<span>(2y^2 + 6) / (y^2 - 1) </span>
<span>Then, if y = 3, just plug in and compute. </span>
<span>I know you can do that!
</span>
The relation between the width and the length is:
l = 3w + 1 --- (1) Perimeter = 2w + 2l --- (2) Put (1) in (2) » Perimeter = 2w + 2(3w+1) » Perimeter = 2w + 6w + 2 Perimeter = 8w +2
Answer:
A, B, C
Step-by-step explanation:
4 - (-5) + 0
4 - (-5) = 4 + 5 (because a negative + negative = positive)
4 + 5 = 9
a, b and c all equal 9
hopefully this helped you!! :3
