Help w algebra problem!!!
Fantom [35]

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

5x=3x+60-20

2x=40

x=40/2

An isosceles triangle has a base of 8 inches and legs measuring 12 inches how wide is the base of a similar triangle with legs m
VARVARA [1.3K]
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.
