I hope this helps! let me know if you need help with anything else! I'd be happy to help you in anyway I can! :)
Area of a triangle is given by 1/2bh where b is the base and h is the perpendicular height of the triangle.
The area is 80x∧5y³ and the height is x∧4y
Thus; 80x∧5y³ = 1/2(x∧4y) b
160x∧5y³ = (x∧4y)b
b = (160x∧5y³)/ x∧4y)
b = 160xy²
Therefore, the base of the triangle is 160xy²
Keeping in mind that there are 5280 ft in 1 mile, and there are 60 minutes in 1 hr and 60 seconds in 1 minute, therefore 60*60 seconds in 1 hr, or 3600 seconds, then.
Isolate for each variable.
1. z= 6 - 10
z= -4
2. y= 48/8
y=6
3. q= 1+12
q= 13
4. 18 x 2= a
36= a
5. r= 7 x 3
r= 21
I think you can try the rest :)
The rise of -7 means that there is 7 less. The fall of 7 would mean that it is also 7 less. So, yes. They are both the same thing.
