you have to solve for X is somthnking
Answer:
Step-by-step explanation:
(a) Let x represent the length of the first side. Then the second side is (x+4) and the third side is (x+3). The perimeter is ...
x + (x+4) +(x+3) = 15
3x = 8 . . . . collect terms, subtract 7
x = 2 2/3 . . . . divide by 3
The third side is x+3 = 5 2/3 inches.
__
(b) For this, we are told the second side is S, so we have ...
S = (x+4)
x = S -4 . . . . . subtract 4 to solve for x
Using this in our expression (in part (a)) for the third side, we have ...
third side = (x +3) = (S -4) +3
third side = S -1
Answer:
Volume = 125 mm^3
Step-by-step explanation:
Here, we want to get the volume of the cube
What we have to do here is to substitute the value of the area
We have this as
:
V = 25^(3/2)
V = (√25)^3
V = 5 * 5 * 5 = 125 mm^3
If we need sections that are 18 ft. long from available 78 ft. long line than we will divide 78/18 =4.(3)
So we will get 4 sections that are 18 ft. long and we will have a remainder of 6 ft line not used.
