I think this is how you do it, each triangle is 3, and the square is .5625 so 3 x 4 is 12+ .5625 so 12.5625, i hope i helped
Find the length of the line from A to C, which would be the radius using the distance formula:
Distance = √(-5 +1)^2 + 1+2)^2)
Distance = √(4^2 + 3^2)
Distance = √25
Distance = 5
The equation of a circle is written as (x-h)^2 + (y-k)^2 = r^2, where h and k is the center point X and y values and r is the radius.
The center of the circle is located at A ( -1,-2) and the radius is 5.
Replace h, k and r with those values:
(x - (-1))^2 + (y- (-2))^2 = 5^2
Simplify to get:
(x+1)^2 + (y+2)^2 = 25
D is the answer because if you calculate the answer correctly. that will be so.
Answer:
4
Step-by-step explanation:
(x)^2+(1/x)^2=18
(x-1/x)^2+2x.1/x=18
(x-1/x)^2+2=18
(x-1/x)^2=16
(x-1/x)^2=4^2
x-1/x=4
Answer:
n+18=7(n-3)
Step-by-step explanation:
Lets replace "A number" with the variable n because we do not know its value!
1) Rewrite the problem as an equation
n+18=7(n-3)
<u>If we want to solve the equation, do the following:</u>
1) Distribute 7 to n and -3:
n+18=7n-21
2) Add 21 to both sides:
n+39=7n
3) Subtract n from both sides:
39=6n
4) Divide both sides by 6:
n=6.5
