Answer:
![864\ ft^2](https://tex.z-dn.net/?f=864%5C%20ft%5E2)
Step-by-step explanation:
we know that
The area of a triangle is equal to
![A=\frac{1}{2}bh](https://tex.z-dn.net/?f=A%3D%5Cfrac%7B1%7D%7B2%7Dbh)
![A=24\ ft^{2}](https://tex.z-dn.net/?f=A%3D24%5C%20ft%5E%7B2%7D)
------> equation A
where
b is the base of the triangle
h is the height of the triangle
In this problem the dimensions of the triangle are increased by a scale factor of ![6](https://tex.z-dn.net/?f=6)
so
the new dimensions of the triangle are
![b=6b, h=6h](https://tex.z-dn.net/?f=b%3D6b%2C%20h%3D6h)
The new area of the triangle will be
![A1=\frac{1}{2}(6b)(6h)](https://tex.z-dn.net/?f=A1%3D%5Cfrac%7B1%7D%7B2%7D%286b%29%286h%29)
------> equation B
Substitute equation A in equation B
![A1=18[48]=864\ ft^2](https://tex.z-dn.net/?f=A1%3D18%5B48%5D%3D864%5C%20ft%5E2)
60mins in 1 hour
80mi per 10min=xmi per 60min
ration and porportion
80mi/10min=xmi/60min
times both sides by 60min
480mi=xmi
answer is 480miles per hour
Answer:
15x - 4
Step-by-step explanation:
Add both of the equations together.
f(x) + g(x)
(3x + 10x) + (2x -4)
Then, combine like terms
3x + 2x + 10x = 15x
15x - 4
Answer:
The answer for 5x - 4 > 12 is B
Step-by-step explanation:
Answer:
B
Step-by-step explanation:
Taking a look at the orientation of the image and post-image, you can see that the rotation done was clearly 90 degrees counterclockwise. It was also shifted down by 3 units, and moved to the left by 2 units, mat the correct answer is choice b. Hope this helps!
