3x = x/2 ---> 6x = x --->6x - x =0 ---> 5x = 0 ---> x = 0
1. You have to make a system of equations.
2. The problem gives the following information:
- <span>. Emi said wow I think the top of that waterfall is about 20 ft more than three times the height of a young Redwood.
- Margaret had a different opinion she said no I think it's about 50 ft less than 4 times the height of the Redwood.
3. So, you have:
y: the height of the waterfall.
x: </span>the height of the Redwood
4. The equations are:
y=3x+20 (i)
y=4x-50 (ii)
3x+20=4x-50
x=70 ft
y=3x+20
y=230 ft
H<span>ow tall is the Redwood and how high is the waterfall?
</span>
The Redwood: 70 ft
The waterfall: 230 ft
6375/pi mm[3] Just took the test, I hope this helps!
First you find the area of the rectangle by multiplying 48 by 40 = 1920
Then find the area of the triangle by multiplying 16 by 48 then divide by 2 = 384
Finally add the two together to get your answer 1920 + 384 = 2304
C 2304 units squared
