Answer:
D
Step-by-step explanation:
Given the 2 equations
4x + 8y = 21 → (1)
y = - 
x + 3 → (2)
Substitute y = - x + 3 into (1)
4x + 8(- x + 3 ) = 21 ← distribute parenthesis on left side
4x - 4x + 24 = 21 ( subtract 24 from both sides )
0 = - 3 ← not possible
This indicates the system has no solutions
96=(x+8)*x*(x-2)=x^3 +6x^2 -16x. Solve to get x= -6,-4,4. Negative distance doesn't make sense, so x=+4. Therefore, length is (x+8)=(4+8)= 12, width=x=4, and height=(x-2)=(4-2)=2.
Hahaha anyway thanks for the free point
Answer:
median
Step-by-step explanation:
The centre of every data set is the second quartile/50th percentile/median
<span>So the question is how to find the volume of a L-block geometrical body. To do that we need to turn an L-block into something we know how to calculate the volume. in the case of an L-block we can use two rectangles because we can calculate it's volume easily, as V=a*b*c and simply sum the two volumes. </span>
