2(l+w)=P
72 x 2= 144
240 - 144= 96
96/2= 48
your answer would be 48in.
<u>check
</u>2(72+48)= 240
144+96= 240
240=240
Rewrite the given quadratic equation in standard form: Kx 2 + 2x - 1 = 0
Discriminant = 4 - 4(K)(-1) = 4 + 4K
For the equation to have two real solutions, the discriminant has to be positive. Hence we need to solve the inequality 4 + 4K > 0.
The solution set to the above inequality is given by: K > -1 for which the given equation has two real solutions.
Two triangles that are proportional to each other and have the same angle are similar.
I can’t see the pic , im so sorry
