Yes, she is correct. If you plug 2 into the equation, you will see this:
(1/2)(2) -7
1-7
= -6
So, the pair of values is (2,-6). Emma is correct.
The question states, "$6.85 per pound find the total cost if Ameila bought 4 pounds".
So you know she bought 4 pounds costing $6.85.
It is equal to 4(6.85).
If you apply the distributive, it will be 6.85+6.85+6.85+6.85.
This is equal to 27.4

- Product rule of radicals: √ab = √a x √b
Firstly, factor out i: 
Next, apply the product rule of radicals here as such:

<u>Your answer is 5i√2, or the second option.</u>
Answer:
The width of the box is 5 in
Step-by-step explanation:
the formula for the volume of a rectangular box of length L, width W and height H is V = L*W*H. Here we know V, L and H and want to find W. Solving this equation for W, we get W = V/(LH).
With V = 180 in^3, H = 4 in and L = 9 in, W comes out to be
180 in^3
W = ------------------ = 5 in
(4 in)(9 in)
The width of the box is 5 in
