Answer:
second one from the top
Step-by-step explanation:
Answer:
2
Step-by-step explanation:
a square is made up of 2 congruent right triangles with the same leg length. we use the Pythagorean theorem to find the length of one of these legs. a^2+b^2=c^2, but we know that the legs are equal in length, so we have 2a^2=(3rad2)^2
2a^2=9*2
a^2=9
a=3
square is made up of 4 of these, so 4*3=12
the perimeter is 12
Answer:13
Step-by-step explanation:2+3+8=13
Product of roots
Let x and y be the roots of given equation.
y+z=-b/a (sum of roots)
z×y= c/a(product of roots)
where "a" is coefficient of x^2 and "b" of x and "c" a constant.
In the given equation is a=1,b=h+4 c=-h^2
so product is given by
y×z= -h^2/1= product is -h^2
