18 feet
1 inch = 6 feet
multiply both by 3 so
3 inches = 18 feet
A-y=4.50x ,4.50 is the slope because for each shirt she sells that is how much she makes and she doesn't have an original value for a y-intercept.
B- 1 ,each tee-shirt she makes she will profit 4.50 for a single so she makes money after the first one.
C-129 ,because you need to find how much each tee-shirt costs in the bunch of 70 and divide it from 800 and round to 129.
Answer:
135m²
Step-by-step explanation:
Perimeter = 2(l + w)
l = w + 6
Substituting for l, gives;
2(w+6+w)
48 = 2w + 12 +2w
48 = 4w + 12
48 - 12 = 4w
36 = 4w
w = 9
Since w = 9, then l = w +6
l = 9 + 6
l = 15
Area = l * w
Area = 15 * 9
Area = 135m²
