It would be (D 8)
Step-by-step explanation:
Answer: the length of the field is 70 yards. The width of the field is 35 yards
Step-by-step explanation:
Let L represent the length of the rectangular athletic field.
Let W represent the width of the rectangular athletic field.
A rectangular athletic field is twice as long as it is wide. This means that
L = 2W
The formula for determining the perimeter of a rectangle is expressed as
Perimeter = 2(L + W)
If the perimeter of the athletic field is 210 yards, it means that
210 = 2(L + W)
L + W = 210/2 = 105
Substituting L = 2W into L + W = 105, it becomes
2W + W = 105
3W = 105
W = 105/3 = 35
L = 2W = 2 × 35
L = 70
Answer:
48 centimetres wide
Step-by-step explanation:
you are at 3
you enlarge it and you get 6
second enlargement you get 12
third enlargement you get 24
fourth enlargement you get 48
if you times 3 by 4 you are not doubling the width each time you enlarge the photo
so it is easier to double it each time you enlarge it
Answer: 8.2 mm
Step-by-step explanation:

Answer:
Step-by-step explanation:
y = -8x - 49
y = -x
- -8x - 49 = -x
- -8x + x = 49
- -7x = 49
- x = -7
- y = - (-7) = 7
