1 x 16 = 16
2 x 8 = 16
4 x 4 = 16
Part 1
Plug in x = 8 and simplify
h(x) = -2x-10
h(8) = -2(8)-10
h(8) = -16-10
<h3>h(8) = -26</h3>
================================
Part 2
Replace h(x) with 14. Follow PEMDAS in reverse to solve for x.
h(x) = -2x-10
14 = -2x-10
14+10 = -2x
24 = -2x
24/(-2) = x
-12 = x
<h3>x = -12</h3>
If x = -12, then h(x) = 14
In other words, h(-12) = 14
------
Check:
h(x) = -2x-10
h(-12) = -2(-12)-20
h(-12) = 24-20
h(-12) = 14

I think the answer is the first one.
Answer:
P(5, 0 )
Step-by-step explanation:
Where the line crosses the x- axis the y- coordinate of the point P is zero.
Substitute y = 0 into the equation and solve for x
2x + 3(0) - 10 = 0 , that is
2x - 10 = 0 ( add 10 to both sides )
2x = 10 ( divide both sides by 2 )
x = 5
Thus P = (5, 0 )

Answer:
24x
Step-by-step explanation:
The total length of all vertical segments is 5x·2 = 10x.
The total length of all horizontal segments is (3x+4x)·2 = 14x.
Then the total length of all perimeter segments is ...
10x +14x = 24x . . . . perimeter of the figure
