Answer:
2√137
Step-by-step explanation:
To find AB, we can use the Pythagorean Theorem (a² + b² = c²). In this case, a = 22, b = 8 and we're solving for c, therefore:
22² + 8² = c²
484 + 64 = c²
548 = c²
c = ± √548 = ± 2√137
c = -2√137 is an extraneous solution because the length of a side of a triangle cannot be negative, therefore, the answer is 2√137.

Answer 45
Step-by-step explanation:
Because 2 times 5 is 10 so 7 times 5 is 35 then add them together.
Answer:
The equation that closely represents the graph is 
Option A is correct.
Step-by-step explanation:
We need to find equation that represents the graph.
We can write equation in slope-intercept form:
where m is slope and b is y-intercept.
For finding the equation we need to find slope and y-intercept
Finding slope
The slope can be found using formula: 
From the graph we can find 
Putting values and finding slope

We get Slope = 60
Finding y-intercept
Using point (0,-160) and slope m = 60, we can find y-intercept

Writing the equation
So, the equation for given graph having slope m = 60 and y-intercept b =-160 is:

So, The equation that closely represents the graph is 
Option A is correct.
