Answer:
Three times
Step-by-step explanation:
Given
Figures: Rectangular Prism and Rectangular Pyramid
Let the dimension of the prism be:
Amount of sand used is the volume (V1) and it is calculated using;
Since the pyramid has the same base area and height as the prism, the its dimension would be:
Amount of sand used is the volume (V2) and it is calculated using;
So, we have:
Substitute lwh for V1 in the second equation
Multiply both sides by 3
Reorder
<em>Hence, the amount of sand used in building the prism is three times the amount of sand used in building the pyramid</em>
Answer: AM=21
Step-by-step explanation:2AM = AB
2(3x+3)= 6x+6
So 6x+6= 8x-6
-6x. =-6x
X' cancel. 6= 2x-6
+6 =. +6
12= 2x
Divide by 2. 6=X
Check 2(3(6)+3). AB = 6x+6. 6(6)+6. 36+6=42
2(18+3)
2(21)=42
Answer:
-2 and -18
Step-by-step explanation:
It is useful to consider the factors of 36:
36 = (-1)(-36) = (-2)(-18) = (-3)(-12) = (-4)(-9) = (-6)(-6)
The sums of these factor pairs are -37, -20, -15, -13, -12.
The factor pair of interest is -2 and -18.
