Answer:
-2 +/- [(sqrt 88)/ 4]
or
0.35, -4.35 to the nearest hundredth.
Step-by-step explanation:
2x^2 + 8x - 3 = 0
Using the quadratic formula:
x = [ -8 +/- sqrt (8^2 - 4*2*-3) ] / 4
= -2 +/- (sqrt 88)/ 4
Number of sides= 10
Side length= 4.6 ( or in this case base)
161 sq inches / 10 = 16.1 area of triangle.
Area of triangle =(b<span>ase * </span>height)/2
16.1=(4.6*h)/2
multiply 16.1 by 2 (cancels the dividing the 2)
32.2=4.6*h
divid 32.2 by 4.6
<span>7 is the height of the triangle</span>
S = n(a1 + an)/2
2S = n(a1 + an)
2S = na1 + nan
nan = 2S - na1
an = (2S - n a1)/n
