Answer:
I love algebra anyways
The ans is in the picture with the steps how i got it
(hope this helps can i plz have brainlist :D hehe)
Step-by-step explanation:
First of all we have to find the slope
y₂-y₁
--------
x₂-x₁.
2 - (-2)
------------
0 - 7
4
---
-7
this is the slope
If you found 15.6895 to the nearest tenth it will be A. 15.7
Units of square inches are never equal to units of cubic inches, so we presume the statement of the problem applies to the numerical values in in² and in³.
The volume of a cuboid of length L, width W, and height H is
... V = LWH
The area is
... A = 2(LW + H(L+W))
You want these to be equal for L=9, W=4, and H=x.
Equating the expressions, we have
... 9·4·x = 2(9·4 +x(9+4))
... 36x = 2(36 +13x) . . . . . simplify a bit
... 36x = 72 + 26x . . . . . . simplify more
... 10x = 72 . . . . . . . . . . . . subtract 26x
... x = 7.2
The dimension represented by x is 7.2 inches.
