So I have the formula for the reflection over the x-axis is from (x,y) to (x,-y), and the reflection for the y-axis is (-x,y). Next, I have the original for A(2,-2), B(2,-6), and (9,-6) which is reflection over x-axis which is A(2,2), B(2,6), and C(9,6). Then, I have A(-2,-2), B(-2,-6), and C(-9,-6) for the reflection over the y-axis. Hope it help!
Answer:
the answer is 180cm for the rectangle
the answer is 126cm for the triangle.
the answer is 880ml for the rectangle.
Step-by-step explanation:
first diagram (rectangle)
area=l×b
15×12
180cm
second diagram(triangle)
area =
third diagram( rectangle)
area=
A week is 7 days. so 16 divided by 7 is 2 with a remainder of 2. so she spent two weeks and two days in south africa.
The answer for the question shown above is the las option, which is: <span>D. 2:3 and 4:9.
The explanation is shown below:
1. You have that</span><span> widths of the two similar rectangles are 10 cm and 15 cm. Therefore:
</span> ratio=10:15
ratio=2:3
2- So, the ratio of the perimeter is:
ratio of the perimeter= 2:3
3- The ratio of the areas is:
ratio of the areas=2²:3²
ratio of the areas=4:9
