Answer: width = 10 ft
Step-by-step explanation:
Area = length × width
Let l be length and w be width
l = w + 4 ........equation (1)
From above formula
140 = l × w. ........equation (2)
Substitute equation (1) into equation (2)
140 = (w+4) × w
w^2 + 4w= 140
w^2 + 4w - 140= 0
By factorization method
(w+14)(w-10)= 0
w=-14 or w= 10
So now width is 10 ft
From equation(1)
l=w+4
l= 10+4
l= 14 ft
Width = 10 ft and length = 14 ft
Radius=8/2=4cm
circular area=4*4*3.14=50.24cm₂
volume=50.24*12=602.88cm₃
The answer is 602.88cm₃
Answer:
i belive its A $15
Step-by-step explanation:
if $3 is 20% and we are trying to find the full 100% then you miltiply 3 by 5 since 20 times 5 equals 100 and when you multiply 3 by 5 you get 15 dollars which is 100 percent of the iteam meaning the regular price.

Answer:
-47
Step-by-step explanation:
For this problem, we can use the rule "two negatives make a positive".
-81-(-34)
= -81 + 34
If you subtract 34 from 81, you find the opposite positive/negative answer.
81 - 34 = 47
Change all of the positive/negative signs:
-81 + 34 = -47
