B) the one that has the sides 4 & 8 and 3 & 6.
The length on both of these rectangles are twice as long as the width
one rectangle goes from a width of 4 and its length is doubled to a length of 8
it is similar to the 3 & 6 because the width of 3 is doubled to get the length of 6
hope this helps
In rolling a die, there are 6 possible outcomes. Each face is numbered from 1 to 6. The possible combinations of numbers so that their sum is 5 is, 1 - 4, 2 - 3, 3 - 2, 4 - 1. Thus, the answer is that they are four possible outcomes corresponding to the given event.

Let L be the low copper alloy and H be the high copper alloy.
We need 0.15L + 0.60H = 0.42 and L + H = 100
L=100 - H
Substituting this into the second equation for L, we get:
0.15(100-H) + 0.60H = 0.42(H+L)
15 - 0.15H + 0.60H = 0.42(H+100-H)
15 + 0.45H = 0.42(100)
0.45H = 42 - 15 = 27
H = 27/.45 = 60 lbs
Back substitution, L = 40 lbs.
