we have (x+4)/(x+5)=(x-3/2)+(x+7/5)
we mutiply by 10 x+5 to get
10x+40= 5(x^2+2x-15)+2(x^2+12x+35)
10x+40= 5x^2+10x-75+2x^2+24x^2+70
0=7x^2+24x^2-45
using the formula we get
(-24+-6sqrt51)/14
(-12+-3sqrt51)/7
expanding (x-2)(x+2) is x^2-4 so we mutiply the whole thing by -1/4 to get -1/4x^2+1=0 so a is -1/4 and b is 0
Answer is -1/4
We know that the diagnols are both sqrt2 so we know that this shape is a square with diagonal length sqrt 2 and since it is a square all sides are equal in length meaning that the side lengths are 1 and the perimeter is 4
because we know one of the anlgles is 90 then we know all the other angles are 90 since oppisite angles are equal so the area is just 12x12=144
