Given (n)=-14
where (n-1) x 7 + 91
(-14) = -14
To put it into an equation, it would be:
340 = 2x - 100
with x being the amount of sophomores at BHSS.
Solve it:
340 + 100 = 2x
2x = 440
x = 220
The number of sophomores at BHSS is 220.
x=9 because the triangle is equilateral which means every side is equal to 60. When you do the math you get 7x-3=60 which is 7x=63 and 63/7=9
Since the formula to find the area of a parallelogram is base times height (A=bh), and you have been given the area and base already, you can set up an equation. Let h=height in this formula. h x 3.4 = 25. Using this formula, to find the height, you would divide 25 by 3.4 and get approximately 7.35 inches. So, your height= 7.35in. Hope this helps!
