Domain is the x values. So based off of that...
D= {-9,-4,3,9}
The range is the y values. So based off of that...
R= {2,2,2,2}
If your teacher says not to repeat then this is your answer below...
D= {-9,-4,3,9}
R= {2}
Hope This Helps!
Answer:
78
Step-by-step explanation:
x + 21 = 3x - 15
- x - x
21 = 2x - 15
+ 15 + 15
36 = 2x
/ 2 / 2
18 = x
2 (x + 21)
2 (18 + 21)
36 + 42
78
I'm not completely sure, but I hope this is right. Undefined terms.
Answer:
You have to find the hypotenuses of the triangle to get the area of the entire area of the shape. Once you have the length of the hypotenuses then you can use that value to calculate the area of the triangle and the area of the box above.
Hyp = sqRoot ( 3.16^2 + 6.32^2) = sqroot(50) = 7.07
Area of Triangle = 1/2 x b x h = 1/2 x 6.32 x 3.16 = 9.99= 10
Are of square above triangle = l x w = 7.07 x 7.07 = 49.99 = 50
Total area = 10 + 40 +10 +50 = 110 SQ UNITS
