Answer:
length = 20 cm
width = 9 cm
Step-by-step explanation:
perimeter = 58 cm
58cm = 2*L+2*w equation 1
L = 3w -7 equation 2
where:
L= length
w=width
so we have:
58 = 2(3w -7) +2w
58 = 6w -14 +2w
58 +14 = 8w
72 = 8w
w = 72/8
w = 9 cm = width
we have:
L = 3(9) -7 = 20 cm = length
Answer:720
Explanation:
Volume= lwh, 8•9•10= 720
Convert 5 1/2 ro improper fraction so 10/2
3/8 + 10/2
Then convert 10/2 into 40/8 by multiplying bu four so they have the same denominator
3/8 + 40/8 =43/8
Well, you can do, 4+9, and 5+9, or, instead of 5+9, maybeeeee, 6+7!
The answer is going to be:
102,500
