Answer:
Step-by-step explanation:
If the circumference of the circle is x cm the perimeter of the square will be 38-x cm.
The area of the square = (38-x)^2.
The radius r of the circle = circumference /2π = x / 2π.
The area of the circle = πr^2 = π * (x / 2π)^2
= x^2/ 4π.
So total area A = (38 - x)^2 + x^2/4π
A = 1444 - 76x + x^2 + x^2/ 4π
A = x^2 - 76x + 0.07958x^2 + 1444
A = 1.07958x^2 - 76x + 1444

bro just use the calculator haha thanks for the points <3
Answer:
x=20
Step-by-step explanation:
Both Angles have the same value, as they are opposite angels.
Set your formula up as
5x+20=3x+60
5x=3x+60-20
2x=40
x=40/2
x=20
If the triangles are similar, the base should be 24 inches. The legs on the first triangle are 12 inches. To get 36 inches (the other triangle), we multiply 12 by 3. 12 x 3 = 36. Because you did that to the legs, you must also do it to the base. 8 x 3 = 24. Therefore, the base of the second triangle is 24 inches.
Answer:
-11
Step-by-step explanation:
-8 = 3 + t
-8 - 3 = t
-11 = t
Hope this helps :)
