Lets call x how wide it is, and write the area equation:
area = width*length
a = (x)(x + 5) = 20000
expand it:
x^2 + 5x = 20000
make a quadratic trinomial:
x^2 + <span>5x - 20000 = 0
</span>lets apply the general quadratic formula to solve:
x = (-5 +- √(25 + 80000))/2
x = (-5 +- 282.89<span>)/2
we take the positive solution:
</span>x = (-5 + 282.89<span>)/2
</span>x = 138.94
therefore the rectangle width is 138.94 m and <span>143.94 m long</span>
First is -1 and 4, second should be no solution and the third is 2 and 6
A:
c=x/2+1500
B:
B=15000
X/2-1500=Total left after charity
F=T-B
F=x/2-1500-15000
F=x/2-16500
C:
X=charity+fam+been
X=x/2+1500+20000+15000
X=x/2+36500
X=(x+73000)/2
2x=x+73000
X=73000
You can't really answer that question without knowing that shape the pasture is
