Answer:
   0.2071
Step-by-step explanation:
It looks like the graph is of the function ...
   y = √(x +8) -2
We know that (-4, 0) is one point on the graph. The other point of interest is at x=0, where y = √8 -2 ≈ 0.8284.
The average rate of change on the interval is then ...
   m = (0.8284 -0)/(0 -(-4)) = 0.2071
The average rate of change on the interval is about 0.2071.
_____
<em>Rougher estimate</em>
The graph goes through the points (-4, 0) and (1, 1), so has a slope of 1/5 = 0.2 on the interval [-4, 1]. We know the graph does not go through (0, 1), so the slope is not as high as 1/4 = 0.25. The curve is concave downward, so the average slope will be higher than 0.2, but we aren't sure how much higher.
A reasonable estimate of the rate of change on the interval is "a little more than 0.2, but less than 0.25."
 
        
             
        
        
        
Step-by-step explanation:
w = 3(2a + b) - 4
w = 6a + 3b - 4
6a = w - 3b + 4
a = 1/6 * (w - 3b + 4).

Answer:
13
Step-by-step explanation:
it's a 5,12,13 triangle 
and we can find the sides by Pythagorean theorem:
a^2 + b^2 = root of c
25 + 144 = 169
root of 169 = 13
