Answer:
pentagon have 5 sides, 5 symmetry lines.
So your answer is Option C.
10:12
15:18
i got this from doubling the first to make 5 = 10 and then that made 6 = 12. the second one was the same but tripled to make 6 = 18 and then that made 5 = 15
Answer:
(4,-1)
Step-by-step explanation:
You can solve this system of equations in a couple of different ways, but I'm going to use the elimination method. If you're solving a system of equations using elimination, you want to have one variable cancel out. In this case, we don't have to change anything because -3y and 3y will already cancel out if we add the two equations together. You can both add or subtract, but it's easiest to add in this case. The equation will be set up like this: 2x-3y=11
+ 7x+3y=25
--------------
After you add them together, you should get 9x=36, which you can solve by dividing both sides by 9. Then, you'll get x=4. This is your x-coordinate. Next, you want to get your y-coordinate, so you can substitute 4 into one of the two equations for x and solve for y. This will get you -1 for y. I'd also recommend checking your answer. Hope this was helpful! :)
Since we are looking for the distance around the edges of the bedroom, we are actually finding the perimeter.
2L + 2W = perimeter where L is length and W is width. Plugging our known information into the equation:
2(13) + 2(12)
= 26 + 24
= 50
Your answer should be 50 feet. Hope this helps!
Answer:
V=35
Step-by-step explanation:
Start by multiplying by 7 on both sides:
V=35
