Answer:
(9b + 3c + 10d)cm
Step-by-step explanation:
Given the sides of a triangle expressed as (2b+c), (7b + 4d) and (6d+2c). The perimeter of the triangle is the sum of all the sides of the triangles.
Perimeter of the triangle = 2b+c + 7b+4d + 6d+2c
Perimeter of the triangle = 2b + 7b + c + 2c + 4d + 6d
Perimeter of the triangle = 9b + 3c + 10d
Hence the perimeter of the triangle is (9b + 3c + 10d)cm

I hope this helps you
Step-by-step explanation:
y=x+9
x=y-9 f^-1 (x)= x-9
x=5 f^-1 (5)=5-9 = -4
f (f^-1))=f (-4)=?
x= -4
f (-4)=-4+9
f (-4)= 5
Answer:
<h2 />
Step-by-step explanation:
x y
1 2
2 4
3 9
4 16
This sounds like a quadratic equation of f(x)=x^2, thus, the range is:
<h3>
R(x): (-∞,+∞)</h3><h3 /><h3>
If the function only has these points, then the range is:</h3><h3>
R(x): [2]∪[4]∪[9]∪[16]</h3>
