Answer:
B. 8
Explanation:
The figure forms a septagon.
The hexagons form the base, and the rectangles attached to them form the sides.
Therefore, in total the solid has two hexagons as sides and 6 rectangles connecting the hexagon to the base hexagon. Hence, in total the solid has
2 + 6 = 8 faces.
Answer:
4/3
Step-by-step explanation:
3y=4x-12
divide by 3 to isolate y
y=4/3x-4
slope is 4/3
Answer: 
Step-by-step explanation: Given expression 
.
In order to find the product of given expression, we need to convert 5,600,000 into scientific notation, because other number is also in scientific notation.
5,600,000 = 5.6 × 10^6.
Therefore, 
.
Now, multiplying 5.63 × 5.6 first, we get 31.528.
And 10^5 × 10^6 = 10^11.
Therefore,
.
<h3>Or 3.1528 × 10^12.</h3>
We have that

Add or subtract.
4m2 − 10m3 − 3m2 + 20m3
=(4m2-3m2)+(20m3-10m3)
=m2+10m3
the answer is the option
</span><span>B: m2 + 10m3
</span><span>Question 2:
Subtract. (9a3 + 6a2 − a) − (a3 + 6a − 3)
=(9a3-a3)+(6a2)+(-a-6a)+(-3)
=8a3+6a2-7a-3
the answer is the option
</span><span>B: 8a3 + 6a2 − 7a + 3
</span><span>Question 3:
A company distributes its product by train and by truck. The cost of distributing by train can be modeled as −0.06x2 + 35x − 135, and the cost of distributing by truck can be modeled as −0.03x2 + 29x − 165, where x is the number of tons of product distributed. Write a polynomial that represents the difference between the cost of distributing by train and the cost of distributing by truck.
we have that
[</span>the cost of distributing by train]-[the cost of distributing by truck]
=[−0.06x2 + 35x − 135]-[−0.03x2 + 29x − 165]
<span>=(-0.06x2+0.03x2)+(35x-29x)+(-135+165)
=-0.03x2+6x+30

Answer:
495
Step-by-step explanation:
1,650 x 0.7 = 1,155
1,650 - 1,155 = 495
(0.7 is the percentage)
Hope this helps!
