Sorry, there is not any square root of -1.
Thank you♥♥
Plug in x=1 and y=2 into the inequality:-
2x + 9y = 2 + 18 = 20
20 is not < 20
so it is not a solution
Answer:
- 7,908
Step-by-step explanation:
Have a nice day :)
1) Formula: area = height * base / 2
2) Call x the height:
height = x
base = 2x
3) State the equation:
(x)(2x) = 49 in^2
4) Solve the equation:
2x^2 = 49 in^s
x^2 = (49/2) in^2
x = √(49/2) in
x = 7√2 / 2 in = 3.5 √2 in
5) Solution:
height = 3.5 √2 in and base = 7√2 in
6) Verification: area = (7√2 in) (3.5√2 in) = 49 in^2
Answer: height = 3.5√2 in and base = 7√2 in.
Answer:
66.56cm = perimeter
Step-by-step explanation:
First find the easy part (the rectangle)
10+10+17+17=54
subtract the part that is not really there (dashes)
54-8=46
Add the height of the circular part
46+8=54
Find the circumference of a circle with a radius of 8
2(8)(3.14)=50.24
Divide by 4 (the circumference is only 1/4 of the the actual circle in this problem)
50.24/4=12.56
Add all of it together
12.56+54=66.56
