Answer:
Elimination
Step-by-step explanation:
The following system of equations can be easily solved by elimination as we can simply eliminate x-term.
Substitution will take a lot of time because you need to move to make either x-term or y-term as the subject then substitute in.
Graphing Method — You need to find the intercepts of both equations. You also have to convert into slope-intercept form which takes a lot of time.
Answer:
w = 9 ft
l = 13 ft
Step-by-step explanation:
2w + 2(w+4) = 44
simplify:
4w + 8 = 44
4w = 36
w = 9 ft
l = 13 ft
Answer: The distance across a rectangular field is longer distance.
Step-by-step explanation:
Since we have given that
Dimension of square = 40 yards
So, Dimensions of rectangle are :
Length = 25 yards
Width = 35 yards
So, Perimeter of rectangle would be
Diagonal of square would be
Hence, the distance across a rectangular field is longer distance.
