B i think im not sure sorry
Length (L): 2w + 3
width (w): w
Perimeter (P) = 2L + 2w
60 = 2(2w + 3) + 2(w)
60 = 4w + 6 + 2w
60 = 6w + 6
54 = 6w
9 = w
Length (L): 2w + 3 = 2(9) + 3 = 18 + 3 = 21
Answer: width = 9 feet, length = 21 feet
1) X+12
2) 2x-5
3) 40-x
4) (x1/3)(12)
5) x0.25
6) 2x:4y
7) 12(x-1)
8) 3[(x)(-8)]
9) 7(2x+3)
10) (x-30)+(y-30)
Answer:
1 hour and 3 minutes
Step-by-step explanation:
Each mile is seven minutes
There are nine miles total
Multiply 7 * 9
7 * 9 = 63
It will take this person 63 minutes 1 hour and 3minutes to run 9 miles
14÷2.99=4.682274
hope this helps!
