Answer:
The best description would be d), at least two sides are congruent.
Step-by-step explanation:
An isoceles triangle is a triangle with two equal sides, so therefore d) would be the best description.
Step-by-step explanation:
it is a cube, like the dice in games. just very large.
as such it has 6 equal sides.
so, the surface area is simply the sum of all 6 side areas.
and because all 6 are equally large, we need to calculate only one and then multiply by 6.
the side lengths of this cube are 9 ft.
so the area of one side is then
9×9 = 81 ft²
and the full surface area is then
81×6 = 486 ft²
Answer:
d. linear; $25/hour
Step-by-step explanation:
From looking at the graph, we have that renting for 2 hours costs $50, for 4 hours costs $100, for 6 hours costs $150, and for 8 hours costs $200. To find out whether the quantities described in the table are linear, we have to see if there is a constant rate of change of price.
For hour 2 to hour 4, we can see that the price increases by $50. This is the same for hour 4 to hour 6 and hour 6 to hour 8. For every 2 hour time interval, the price increases by $50. Therefore, there is a constant rate of change and the quantities described in the table are linear.
Now we have to find the constant rate of change per hour. We know that the price increases by $50 every 2 hours, so, by dividing both the hours and price increase by 2, the price increases by $25 per hour. So the constant rate of change is $25/hour.
Linear. $25/hour
Answer choice d.
I hope you find my answer and explanation to be helpful. Happy studying.
Answer:
6x + 3y
Step-by-step explanation:
3x + 3 (x + y) ➡ 3x + 3x + 3y ➡6x + 3y
