Well the area would be 49 because Area is LxW so 7x7 = 49. That is how you find area. Perimeter is L+L+W+W so all the sides added together so the perimeter on this shape would be 25 because 3+7=10 and 7+4=11 10+11 = 21 then + 4 = 25
Hope this helps!
The answer should be B if I am correct
we know that
Domain:
Domain is all possible values of x for which any function is defined
For finding domain from any graph , firstly we will find smallest x-value and then largest x-value of curve
and that would be domain
Here , we have
smallest x-value is -3
but there is a hole at x=-3
so, function is not defined at x=-3
largest x-value is 1
so, domain would be

Step-by-step explanation:
we solve for x
15x-(2/x)>1. /*x
15x^2 -2 > x. /-x
15x^2 -x -2 > 0
Solve the quadratic at zero
15x^2 -x -2=0
using the quadratic formula
x1,2 = [1+-sprt((-1)^2-4(15)(-2))]/2(15)
= [1+- sqrt (121)]/30
= [1+-11]/30
x1= 12/30= 2/5
x2= -10/30= -1/3
therefore this positive parabola is greater than zero or positive when
x< -1/3 and x> 2/5
