Surface area of a cube = 6l²
Now given length = l = 8 mm
= 6*8² = 6*64 = 384 mm².
Thank you !!
Answer:
5
Step-by-step explanation:
We are given with the rectangle shaped deck which has a width of 29 feet and a perimeter of 134 feet. the perimeter of a rectangle is equal to twice the sum of length and width. hence the equation goes :
134 ≤ 2* (29 + L)
67 <span>≤ 29 + L
38 </span><span>≤ L
length should be greater or less than 38 feet</span>
Answer:
x = 8
Step-by-step explanation:
-1/4 (2x + 8) = -6
Multiply both sides by -4.
2x + 8 = 24
Subtract 8 from both sides.
2x = 16
Divide both sides by 2.
x = 8
