Answer:
3.25
Step-by-step explanation:
Perimeter of triangle = 3(5) = 15 cm
Perimeter of rectangle = 2(2x - 3 + 4)
Perimeter = 2(2x + 1)
Perimeter = 4x + 2
4x + 2 = 15
4x = 15 - 2
4x = 13
x = 13/4
x = 3.25
Answer:
26
Step-by-step explanation:

Then your problem is m(9)=2(9)+8
Now it is m(9)=18+8
Then add 18 and 8 for 26

Answer:

Step-by-step explanation:
The equation is 
Where h(x) is the height and x is the distance from where you are standing
The new distance is "1 foot farther from where you are standing" -- so this affects x, which becomes "x+1".
We simply replace x with x +1 in the equation of h(x) and simplify if possible:

THis is the new function.
