The area was originally 3*5, or 15 cm^2.
When the sides were enlarged, they were all multiplied by 3. The new sides are 3*3, or 9, and 5*3, or 15.
The new area is 9*15, or 135 cm^2.
If you divide 135, the new area, by 15, the original area, you get 9. So, the area increased by a factor of 9.
You can set up two equations from the information given. I will set them up for you:
32 = 4x + 2y
36 = 5x + 2y
Let's solve the first equation to come up with a value for y.
32 = 4x + 2y
32 - 4x = 2y
16 - 2x = y
Now we plug y into the other equation.
36 = 5x + 2(16-2x)
36 = 5x + 32 - 4x
4 = x
Now we have our real x value and we can plug it into the first equation.
32 = 4(4) + 2y
32 = 16 + 2y
16 = 2y
8 = y
Since x = 4 and y = 8, you get the final coordinates of (4,8).
Your answer is the second statement provided above.
Answer: 500
Step-by-step explanation:
300 squared plus 400 squared is x squared so just do the square root of 300 squared plus 400 squared
bearing in mind that lines with an undefined slopes are vertical lines, Check the picture below.
