K' (6,-4)
L' (0,-7)
M' (6,-10)
N' (8,-7)
Step-by-step explanation:
As we are rotating 180 degrees, We just need to change the sign of each of the points.
Answer:
5x-8=90
Step-by-step explanation:
Thale’s Theorem
5x-8=90
Answer:
92.5
Step-by-step explanation:
Lets say, first number = x
Second number = 3x+7
Total = 49
(x)+(3x+7)= 49
4x+7 = 49
4x = 42
x = 42/4
x= 10.5
x= 10.5
3x+7 = 3(10.5)+7 = 92.5
Hope this helps!!
Answer:
620 cm²
Step-by-step explanation:
First I'll describe the net. There are 3 rectangles and 2 triangles. The triangles are identical and 2 out 3 of the rectangles are the same.
So, we know that the two similar rectangles have measurements of 13cm x 10cm. So, that's 130 cm² for one such rectangle. Add the other one and we get 260 cm².
The bottom rectangle has dimensions of 10cm x 24 cm, or 240 cm². Add that to our previous total and we'll get 500 cm².
On to the triangles. Now, we know that 1. these are isosceles triangles, and 2. they have a height of 5 cm. We can pretend to cut them in half at their highest point, which would give us 4 triangles with height 5 and length 12. Now, if you put two identical triangles together, it's a four-sided shape, and you can just multiply length by width. Let's do that.
Now we have 2 rectangles, each with width 5 and length 12. Calculate the area for each, and now we have 2 rectangles with area 60 cm². Add them together....120cm².
Add that to our previous total, and we'll get 620 cm². That should be the surface area of your prism :D
Answer: Hope this helped(tried my best thinking what the question was asking)
x=0
y=-3
Step-by-step explanation:
(Im going to add and subtract)
Add:
14x-12y=36
14x+9y=-27
28x-3y=9
Subtract:
-14x+12y=-36
14x+9y=-27
21y=-63
y=-3 (substitute in first equation)
7x+18=18
7x=0
x=0
SO
y=-3 and x=0
