<em>Answer:</em>
<em>d = 10</em>
<em>Step-by-step explanation:</em>
<em>3/4(6 + d) = 12</em>
<em>(18 + 3d)/4 = 12</em>
<em>18 + 3d = 48</em>
<em>3d = 48 - 18</em>
<em>3d = 30</em>
<em>d = 30 : 3</em>
<em>d = 10</em>
That triangular prism will be half the volume of the rectangular prism that's 7 by 6 by 8.
(7)(6)(8)/2 = 168 cubic units
Choice B
Answer:
500
Step-by-step explanation:
25c+450=12,950
-450 -450
25c=12500
divide by 25 on both sides to get c alone
c=500
Let
x--------> the length side of the square base
h--------> the height of the box
we know that
<u>the volume of the box is equal to</u>
so
<u>the surface area of the box is equal to</u>
(remember that the box is open)
area of the base=
Perimeter of the base=
height=(h) m
substitute
we know that
the value of x can not be negative and the denominator can not be zero
therefore
<u>the answer is</u>
the domain of SA is x> 0
the domain is the interval-------------> (0,∞)
