Given:
a = 2 and b = -2.
To find:
The value of 
.
Solution:
We need to find the value of expression at a = 2 and b = -2.
Substituting a = 2 and b=-2 in , we get
Therefore, the value of expression at a = 2 and b = -2 is 20.

Answer:
it's 12 x12 which is 144, then 35x35 which is
1225. 144 +1225= 1369. square rooted it's 37
Step-by-step explanation:
Answer is 37

Answer:
y < 1/2x - 3
Step-by-step explanation:
You can write the inequality equation for the graph using the form y = mx + b. The inequality line has a y-intercept at (0,-3). This means b = -3. It also has a slope of 1/2 since the line moves up 1 and over 2 to the next point on the line.
This means the lines equation is y = 1/2x - 3. But since this is an inequality, you must use an inequality sign. Since the line is dashed it is not equal to. Your options are < and >. Use the point (0,0) to test which sign is appropriate.
y < 1/2x - 3 y > 1/2x - 3
0 < 1/2(0) - 3 0 > 1/2(0) - 3
0 < -3 0 > -3
The answer is y < 1/2x - 3 since (0,0) doesn't make it true and (0,0) is not shaded in the graph. This means it is not a solution.
