p(x)*q(x) = g(x)^2-f(x)^2 = x^6-2x^3+1-x^2-10x-25 = x^6-2x^3-x^2-10x-24
h=4s so 5s = 20.6 which means s=4.12 and h = 4s=4*4.12 = 16.48
Let x^y=a,y^x=b. Then, a+1=b, 2a=b+7 so 2a=a+8 which means a=8,b=9 so x=2,y=3.
We have 3
Slope of l_1 is -3/4 so slope of l_2 is 4/3 which means l_2 is y=4/3x+b and we get 7 = -20/3+b so b = 41/3 which menans m+b=4/3+41/3 = 15.
f(3)=3
f(7)=5
f(15)=7
-16+256=240 so it is -16.
(3x+4)(2x+5)=38 so 6x^2+23x+20=38 so 6x^2+23x-18=0 so x=2/3 and the width is 6.
(1/2)^2=1/4
We have that 2+x>=0 so x>=-2, and also 1-sqrt(2+x)>=0 so sqrt(2+x)<=1 so either 2+x<=1 or 2+x>=-1 and those mean x<=-1, x>=-3 so it is -2<=x<=-1.
